2. What’s new in v13.0.5Enhancements – New Options – New Features

TASK Manager

Barrier Allow the addition of more than one "Barrier contact" items. 19045

SCRIPTING

Impactors definition fields are now editable by scripting.



3. Known Problems resolved in v13.0.5

GENERAL

Open In v13.0.4 a “fixing operation” was introduced regarding CONS and 3D curves, during OPENing ansa files or CAD data files (step, iges, catia, etc). This operation caused unaccepted delay in opening some ansa files.

A new approach is now introduced which significantly reduces the “opening” time.

19412

Quality criteria Improper writing of quality criteria in files (*.ansa_qual) and ANSA.defaults by v13.0.4 on Windows platforms.

19570

GUI Settings Starting ANSA v13.0.4 for the first time (there was no .BETA or version_13.0.4 folders) on some Windows platforms was failed (only the first time) due to the “Copy settings of the previous version”.

If the folder version_13.0.4 with the ANSA.xml and ANSA.defaults (copied form v13.0.3 for example) was manually created, ANSA v13.0.4 was normally started.

19605

Selection tool When the option “select nodes from elements” (e.g for the function MESH>GRIDs>ALIGN) had been enabled and later a function that need to select “Edges” (MESH>SHELL MESH>RECONS) were activated an abnormal exit occurred.

19553

Output Wave-Front : fixed error that created corrupted ansa files due to renumbering of nodes.

TRANSF. Rotate: starting the operation with '-' gave wrong the results for “Total Rotational Angle”.

19582

CHECK The Pause/Break key stops now the 'checking' operation. 18772

DataBase Browser

Modify Fixed error that caused abnormal exit when using the “command” subif ($,'\:','++')

on Windows 64 bit platforms

19896

The 'if' expression did not work in some cases for defining a variable value in a field, e.g. magnitude for Pressure.

19946

Fixed error regarding calculation of a value given by an 'expression' within a field. e.g. The magn field in DLOAD card of ABAQUS.

15412

15320

BETA CAE Systems S.A. Known problems resolved in v13.0.5 3


CAD data Translators

Unified Translator

CATIA

Fixed error that caused abnormal exit when ANSA_TRANSL was used that called COMPRESS during a translation session that had no hidden or converted entities.

JTOpen

Fixed error on Windows platforms that caused illegal termination due to memory corruption.

TASK Manager

Include files It was not able to export a read-only include contained in a Task include (e.g. to point to the path where the barrier is located) if it was empty. This is now allowed.

19434

Assembly & Connection Manager

Seam Lines Shells creation failed in rare cases where connection line should be realized by reconstructing the shell mesh with 'single' target edge number.

'Loose Ends' enabled: Adjusting feature line edges to connection curve's limits would not work when feature line was only 1 edge.

18168

TOPO

FACEs DELETE : removing faces that were related to volumes could cause abnormal exit in particular cases.

19909



BATCH Mesh Manager

The “Triangles percentage” criterion was wrongly caused “Error” quality report although there was not error.

19477

Holes Treatment: in some cases when there was “Target Diameter” value the Zone creation failed.

MESH

ELEMENTs WRAP: Could not rename the part that was created after wrapping. 19408

PENETR. : Freezing the SOLID property of a volume mesh during depenetration would not work; nodes of the solid elements moved.

Volumes LIST : Fixed error that caused abnormal exit when Volumes>Map property list was pressed.



DECKs

KINEMATICS Automech : fixed error that caused abnormal exit on particular cases. 19562

SETs Fixed error related to CONS that are loaded into a SET. If the selected chain of CONS had segments of different Faces that were “joined” into one Macro area, the nodes of some segments were ignored.

NASTRAN

Input Fixed error that blocked ANSA while reading particular nastran files having DMIG definitions.

19470

D.INFO Corrected mass calculation when the property field "NSM" had a valid value AND a BC set was defined also. The calculation of the total mass took into account twice the NSM (in NET MASS and in NSM mass).

19576

ABAQUS

Fix in reading Abaqus *xxx_TEST_DATA under *MATERIAL contents. The imported *HYPERFOAM was converted to *HYPERELASTIC (if defining BIAXIAL, PLANAR, UNIAXIAL and VOLUMETRIC test data).

(v13.0.4)

19660

LS-DYNA

Property *SECTION_BEAM: Fixed error that caused abnormal exit when editing an SECTION BEAM card with valid IRID definition and changing the ELFORM into 2.

Material Material type 187 (MAT187 MAT_SAMP-1):

Fixed edit card regarding the position of field "LCID_LC" that is moved to correct position.

Now the "LCID_TRI" is visible in the edit card and is not overlapped by "LCID_LC" field.

Output *INCLUDE_TRANSFORM did not offset correctly *ELEMENT_SEATBELT_RETRACTOR and *ELEMENT_SEATBELT_SLIPRING

19721

Input Fixed error that caused unexpected exit when reading Dummy model in combination with *INCLUDE_TRANSFORM

(v13.0.4)

19911

Fixed reading of *DATABASE_CROSS_SECTION_SET regarding the "xSID" sets, which must contain proper type of entities; e.g. between 2 sets with the same ID for "BSID" set, the one that contain beams will be used.



PAM-CRASH

INPUT CNTAC_/ TYPE 43: XDMP1 field was wrongly read; its value was overwritten by the FSVNL value.

19362

CHECK CONTACTS : when 1D elements (e.g. BEAM) existed in master surface caused abnormal exit.

19797

Dummy When rotating a dummy with pam JOIN elements the information about the angles of the joints were not updated.

19846

CFD decks

STAR CCM

CFX

OpenFOAM

The interior faces lost their orientation. 19697



MORPH

MODIFICATION FIT > SURF.: The projection of the selected morphing edge was failed on 2nd order Solids.

19609

SCRIPTING

Script function "PickEntities" works now properly when search type is a connection entity. 12042

AssignConnectionSettings : improvements for the the connection attribute strings

The first part (connection type), i.e. AdhesiveLine_ SpotweldPoint_ has to end in “Underscore”. However the rest line with the FE-Repr accepts now lower or upper dash

i.e. SpotweldLine_RBE3_HEXA_RBE3_PSOLID_ID and SpotweldLine_RBE3-HEXA-RBE3_PSOLID_ID are both valid.

Mind that blanks are not allowed.

19548

GetPartDepth script function: Wrong result of Parent and Depth ; it did not return 0 (zero) if no depth was found.

19387

Problem with the foreach session command. The following session did not work:

foreach file ( /home/*.igs ) {OPEN:$fileMESH>SHELL MESH>FREE :}

1. Introduction

This document contains all information about features improvement, new features added and problems fixed during development of ANSA from version 13.0.3 to version 13.0.4.

ANSA v13.0.4 will ask to load the settings that exist in the “settings folder” of the previous version, i.e. /home/.BETA/ANSA/version_13.0.3 or older v13.0.x) when will start for the first time.

In the /config/ folder of the ANSA installation, there are the following files with user (*.xml) and run-time settings (*.defaults):

ANSA.xml This is the suggested default GUI settings. Load it from the $ANSA_HOME/ANSA.xml






NOTES:

• ANSA files saved by ANSA v13.0.4 CAN be opened by v13.0.3 but cannot be opened by older ANSA versions.

Release History:

v13.0.4 2010.03.29

v13.0.3 2009.12.18

v13.0.2 2009.10.01

v13.0.1 2009.05.25


v12.1.6 2008.12.21





GENERAL

When launching a new version of ANSA for the first time (starting v1304 and there isn't the .BETA/ANSA/version_13.0.4) user can load the GUI settings from the previous version (if click Yes) or get the suggested from the ANSA installation (by click No).

If there is no older version's “settings folder” and .xml file ANSA automatically starts with the suggested default settings.

Similarly using the -gui option (e.g. ansa1304 -gui cfd) is able to read in the respective settings from the previous version's folder, if exist.

File > Open Read CAD data: IGES, STEP, VDA-FS

The creation of SETs, based on named entities, is now controlled by the new option that is added in Windows>Options>Settings>CAD input topology.

This option affects also the CAD-to-ANSA translation, e.g. CATIA to ANSA

18982

Selections Nodes Selection:

When selecting nodes for a function, a new tool button is available that enables the selection of nodes from entities. This provides the Area selection options.



Windows > Options

GUI Settings

A new button is added to enable, when it is active, Auto-saving of GUI settings in ANSA.xml file when Quit ANSA.

Shortcuts Modifier key 'Shift' cannot be used for shortcuts any more., e.g. Shift+A. However can be used together with other modifier key, e.g. Alt+Shift+A

Modules > User Menu

It is now allowed to change the Button's custom name of the User menus independently of the custom names you use for their original buttons.

CAD data Translation

JT-Open The extraction of geometry of type "XTB-rep” is now supported. 10872

Data Management

Change Representation : the respective dialog box pops up, even if no DM_Root has been defined, allowing the selection of the default representations: Dont Use/Use/Spc/Lumped Mass/Trim.



Connection Manager - Assembly

Connectors New search option for Connectors under "Holes": zones = Out

in order to 'grab' only the outer nodes of a zone.

17886

CHECK CONNECTIONS: "Spider positioning" checks the projections of connections and flags an error if they are too close to perimeters or features.

In order to perform the check, the user may specify

- a Diameter of the spider ( if blank, it'll use the connection's Diam - or calculate it using the thickness-to-diameter mapping )

- a Zone width ( blank means zero )

- a Distance from perimeter (blank means zero )

The check will report an error if the distance between a perimeter & the projection is less than (diam + zone + perim_dist)

! Note : this check works only on shells ( meshed macro area and/or FE-mesh).



MESH – Batch Mesh

SHELL MESH > RECONS: reconstruct on TRIA mesh refines mesh in order to improve quality.

MESH>SHELL MESH> PARAM. > Defeaturing

BatchMesh> Mesh Parameters>Defeaturing>

New parameter “Maintain sharp edge ribs" to handle the sharp edges on ribs, as depicted below:



SAFETY

Pedestrian - The New 'EU Phase 2' (GTR) regulation is now supported.

- The EuroNCAP v5.0 has been added.

- the 'EC.Reg' renamed to 'EU Phase 1'



LS-DYNA

D.UTIL CHECK > SPOT WELDs : a new Fixing option has been added to Rigidize the nodes of the spotweld.

For example, if the Spotweld Beam is defined of the surface of a Rigid Part, then the Fixing creates a *CONSTRAINED_EXTRA_NODE between the Beam's node that “touches” the rigid part and this rigid part. If a Spotweld Beam is defined on a shell element whose node(s) participate in a *CONSTRAINED_NODAL_RIGID_BODY then the fixing will add in the Nodal rigid body the Beam's node that “touches” the shell element.

CHECK > PENETRATION : No penetration is searched between master/slave rigid bodies parts.

PAM-CRASH

CONTROL CONTROLS > OTHER : Support of INPUTVERSION = 2009 in the drop menu.

16126

PERMAS

Support of $GEODAT SOLID keyword 17990

15001

18886

CONTROLS PARAMS : picking from the screen the control points and highlights the parameter in the list.

19153



SCRIPTING

New built-in session function:

MESH_SHELL_MESH_RESHAPE_VIOLATING

Added script function "GetSpwDiamFromThickness".

Calculates a diameter value, for a connection point with zero diameter, by Spot Weld Thickness to Diameter Map.

SaveRepresentation() script function. The functions last argument has been enhanced, Accepted values are:

0 : In case current representation is found in DM, the save procedure for the particular part should be skiped.

1 : In case current representation is found in DM, it should be overwriten.

2 : In case current representation is found in DM, a new study version should be created(applies only to parts).

Rigidize new built-in script function

matrix multiplication and DotProduct were changed:

multiplication accepts matrices other than square, and DotProduct vectors with length other than 3

Script collection

ReportConnectionsOfParts :

Reports in csv format the number of connections in which every part/group participates, according to the number of flanges that they connect.

CheckDynaContactsFromSolver :

Reads an LS-DYNA message file that is specified by the user. The following warnings are reported in the Checks List: -Penetrating nodes of sliding contacts -Untied nodes of tied contacts -Nodes of tied contact that will be moved by initialization -Nodes of tied contct that belong to both master and slave sets.

The functions MeasureAngleNodes, MeasureAngleShells, MeasureDistance are removed.

The new built in function CreateMeasurement supports now all kinds of measurements.

18401

18199

17128

MAP: If the map volume mesh is created with straight transition between the two faces, since the upper is a linked face, Ansa always reported, that the master and the slave macro areaswere not compatible.

If the linked macro was selected at first, map worked.

16815

MAP : fixed error that caused abnormal exit when Map was applied to 2nd order mesh.

18596

LAYERS : the “Layer Area” window has been changed (improved) in order to avoid bad performance in case of big number of listed Properties.

Seatbelt: Fixed error that blocked ANSA when generating Seatbelt Elements that were about to be placed into a new Part but were not (The Part Manager was closed instead).

19098



NASTRAN

File> Output Fixed error that removed the existed ZOOFS values of the CQUAD and CTRIA when they were converted to CQUADR and CTRIAR at output.

18058

NSML was applied to sets that were defined by property. In the exported file, both PSHELL and BCPROP entries appear.

18042

D.INFO calculated the NSML mass twice in the total mass report.18198

ABAQUS

FILE> Input Undefined properties get now materials with correct ids (mat-id < 10000000)

Fix error that caused abnormal exit when reading ABAQUS H350 v7.1 dummy.

19172

When beam orientation is not defined in the abaqus input file, the default values are now assigned in order to avoid “incomplete orientation” when convert it to other deck file within ANSA.

18278

File > Output Wrong output of *DISTRIBUTING COUPLING defined with solid facet set is fixed.

18376

D.UTIL CHECK > CONTACTS ORIENTATION: Improve the proximity detection and correct several failed cases.

18755



LS-DYNA

Input Correction on reading the initial angle of the joints in latest FTSS dummies (v7.1) that has a new definition.

18589

Fixed error when reading twice an Ls-Dyna input file that contained *INITIAL_AXIAL_FORCE_BEAM with "sets"= "keep-old". The second keyword did not read in.

When importing a file with *DATABASE_CROSS_SECTION_PLANE the "PSID" should be a set that contains only parts. In case 2 sets with the same ID are imported the Set that contains parts will be used as PSID, following exactly the LS-DYNA rules.

Fixed error that caused abnormal exit when importing *INCLUDE TRANSFORM with OFFSET ID and *MAT_ADD_EROSION has to be offset.

19180

Output *DATABASE EXTENT BINARY : the values given in fields NINTSLD, NEIPH of the respective card, were wrongly interpreted in the exported dyna file on IBM-AIX operating system.

On HP-UX platforms an error caused abnormal exit at opening/closing the DATABASE EXTENT BINARY card.

18156

CONTACT : in case the MSTYP and/or SSTYP was type=Part_Set and is defined by Elements and/or Faces then it was exported “empty”. This is fixed and now the PART of the included Elements/Faces is written in the *SET_PART_LIST that is exported.

Moreover, the drawing of the Contact complies to the “Part_Set” type and the entire PART is highlighted (as it is about to be exported).

19044

The SHRF value for BEAM in ANSA.defaults was not taken into account; the TSHELL value was taken instead.

18216

Elements

Transformations

*Element_Mass - *Element_Inertia: the Inertia values were not get transformed (updated) due to transformations (e.g. by the Geometry>TRANSF. function) if they where defined in the global coordinate system.

BOUNDARY Fixed errors related to *BOUNDARY_PRESCIBED_MOTION handling:

– The Reference on a node that was used as “orientation node” for relative displacement of a *BOUNDARY PRESCIBED MOTION, did not report the boundary entity.

– it was not allowed to PASTE a 'free' node that was used as “orientation node” for relative displacement to another node. This should update the *Boundary card with the new node id..

– it was not allowed to define a *BOUNDARY PRESCIBED MOTION with VAD=4, relative displacement, without the “optional orientation nodes” (NODE1 – NODE2).

18268

MATDB Unnecessary ANSA Comments written out when saving a MATDB caused ANSA to exit when the Material Database was read back into ANSA.

18064

Materials It was NOT allowed to assign MAT 77 to a *SECTION_SHELL within ANSA.

18664



Auxiliaries *DEFINE_TABLE : Fixed error related to wrong sorting of curves within a table if scientific format was used for x values.

When Editing the Table card, the Auto sorting based on x values was performed, but in a wrong way: The number 1.6E-7 was considered bigger than 0.04.

Exiting the card with OK or Cancel produced the erroneous deck file. If the Table card is not edited no problem occurred.

18309

*DATABASE_HISTORY_SPH : when defining such an entity it was allowed to pick any nodes. Now only nodes from SPH elements can be selected.

17285

Fixed error that did not allow to select a SECTION_BEAM_ELFORM_6 to create a *DEFORMABLE_TO_RIGID_AUTOMATIC. However, the specific type was selectable in *DEFORMABLE_TO_RIGID and *DEFORMABLE_TO_RIGID_INERTIA.

18475

*RIGID_WALL_GEOMETRIC_PRISM were wrongly displayed. The LENP value should be on the negative n (normal vector) and not the positive.

17896

Safety Trans Dummy: Fixed error regarding the Dummy model positioning and the proper Kinematic_Definition update of FTSS dummies and NULL elements that were not belonging to KIN_RBODYs.

18240

KCONF Dummy Handling

KCONF >'Conv to *NOD_TRSFM' : fixed error related to the Set contents that is exported.

CHECK SPOT WELDs : the function detected as error any type of solid that connected to a *CONSTRAINED_NODAL_RIGID_BODY. It did not distinguish between spotwelds and solids elements modeling parts.

17290



PAM-CRASH

Mesh Quality Wrong calculation of angle criterion for PAM-CRASH is fixed. 18129

TRANSF. Copy: :Error while copying FRAME IAXIS 0; the new Frame had IAXIS =1. 18157

18397

RADIOSS

File > Input Fixed error related to Radioss files having /SUBSET keywords on IBM AIX 5.2 RELEASE version.

File > Output

Fixed error regarding the material card update according to CONTROL>ACTIVE VERSION.

When switching from CONTROL the ACTIVE VERSION (e.g. from v4.1 to v5.1 and vice versa), the Material Card was not updated. Specifically, in LAW36 Material Card, the 2 fields (Ipfun and Fscale) were always displayed although they shouldn't.

17099

D.UTIL CHECK > CONTACTS : When shells and solids had common nodes , the 'facet thickness' of the solids was not calculated correctly.

17676



PERMAS

18463

NESTED > New: there was no auto-creation of the REFGRID (at the cog of the nested element).

18474

MODIFICATION EXTEND : fixed error that caused unaccepted results. 18076

CROSS SECTION

TOPO>CROSS SECTION> Cut: in case a Cross Section was defined by “cutting” on FE - Model and Geometry the Cross Section was generated only on the FE.

17926



SCRIPTING

CreateEntity, CreateEntityVa: When called for NASTRAN Bc's (force, spc, etc,) for a deck other than NASTRAN (e.g. PERMAS $CONLOAD) caused abnormal exit.

PositionPedestrian : In case the XZ plane of the headform did not coincide with the global XZ, although the headform was correctly positioned, the rotational components of the transformation calculated were wrong.

11204

PickNodes : fixed the wrong return of PickNodes function after picking nodes on perimeters/Faces.

18611

AddPartToMeshingScenario : The first item sent to script function failed to be added if it was a property.

Also, the function returns now 0 if the item is not added to the scenario.

18628

ChangeElemType : fixed error that caused abnormal exit when used to convert CONSTRAINED_NODAL_RIGID_BODY to CONSTRAINED_INTERPOLATION.

18687

PrintToFileVa : when executing the function for the first time, it worked OK. However, If executing the function for a second time, ANSA saved the image of whatever the monitor displays at that moment (and not of the ANSA graphics window).

18750

VolumesDetect : the function now returns 0 if no volumes are detected and N for the N number of volumes detected.

17781

D.INFO: correction of the image generation that was not the visible model. 18049

Tel. : +30-2392021420Fax. : +30-2392021417



ANSA v13.0.3 Release Notes December, 2009

1. Introduction


In the /config folder there are the following files with user (*.xml) and run-time settings (*.defaults):

ANSA.xml the first time you launch ansa_v13.0.3 this ANSA.xml will be loaded






NOTES:

• ANSA files saved by ANSA v13.0.3 cannot be opened by older ANSA versions.

• A new directory is created “tutorials_and_examples” with data that have been extracted from the “docs” directory. The “optimization_examples” folder is now placed in the examples sub-directory. Mind to download the extra file ansa_v13.0.3_tutorials_and_examples** that contains now the tutorials and examples.

• Updated / New documents

•Updated CFD Practices documentation

•Enhanced Script Collection

•New Tutorials:

Batch Mesh (./tutorials_and_examples/tutorials/TOPO_MESH/batch_mesh/)

Release History:

v13.0.3 2009.12.17v13.0.2 2009.10.01

v13.0.1 2009.05.25


v12.1.6 2008.12.21





GENERAL

Ansa -help Calling ANSA with the -help option [ ansa -help] in a terminal (command prompt) prints the starting options of ANSA and CAD-Data translators in the terminal (command prompt)

17473

Numbering rules

Special numbering rules are saved in the ansa file if the entity that has the rule is saved also.

Database Browser

Advanced filter The option "unused" has been added as built-in filter. It isolates the listed entities that are not referenced by any other entity.

It can be called also in the “Simple” filter line-edit.

14119

TASK Manager

Nastran The BCONTACT case control command is supported.

Support of “Contact” task item for Nastran loadcase

Data Management

The Smaragd PLMXML v6.0 is supported.



Connection Manager

File>Output

ANSA_Comments

The “Comment” and “Name” attributes of the Connections, as they appear in the respective columns of the Connection manger, are exported as ANSA_COMMENT.

14995

Seamweld For the FE-Representations:

RBE2, RBE2-CBEAM, RBAR-SHELL, NASTRAN CWELD, Y-JOINT-SHELL, OVERLAP-SHELL, EDGE-WELD-SHELL, Y-JOINT-FEMFAT, OVERLAP-FEMFAT, EDGE-WELD-FEMFAT

the check box “Loose Ends” has been added.

When it is "ON" , there will be no split in the mesh to make it match the connection line.

FE-Representations: RBE2 , RBE2-CBEAM , RBE3

When a cut is performed ( or elements split , when the new 'Loose Ends' flag is off ) , it is followed by a local mesh reconstruction.



MESH

VOLUMEs MESHV > DELAUNAY: The function takes into account the Size boxes.

MESHV > DELAUNAY: Improvements to avoid swaps on boundary for better quality.

The Delaunay volume mesh takes into account the Size boxes.

Batch Mesh

All Mesh Parameters are now converted according to the current UNITS (Windows>Options>Settings>Units)

– When changing the units all parameters that are distances will be converted according to the new units ( global mesh, volume and layer parameters).

– Read parameters (ansa defaults, *.mpar, *.lpar): reading distance values are supposed to be in [mm], so conversion is done if the current units in ANSA are not [mm].

– Saving parameters : all distance values are saved in [mm], regardless the current selected units in ANSA.

!!! Mind to check the “Scale Model dimensions” in order to comply the changes between 'mesh parameters / criteria values' with the 'model's size'.



ABAQUS

ELEMENTs Support of C3D10I element type of Abaqus v6.9 16245

LS-DYNA

KinematicsSetParameters : Support move by actuator joint in scripting 17415

BrachEntity : supports now the creation and modification of PASTED_NODES.

CreateMeasurement : new built-in script function



Script collection

ShellSet2FacetS

Select from a list, sets with faces or shells. In the case that there are solids elements connected to these faces/shells, ANSA will add or create a new set (depending on flag) with the facets of these elements.

TriasWithCommonEdge

Finds trias with common edge

ParseDirectoryTree

Searches recursively in directory for finding files of specific type

SelectionAssistantConnectorsGEBs

Generates the button "SelAssistantCntrGeb"in the User Script Buttons menu, under the custom category "AUXILIARIES".This function popsup a custom user interface. The user is prompted to selected the entity types whose visibility he/she needs to control. Available entity types are: Connectors, GEB_BC, GEB_OR and GEB_MT. The visibility of the entities is controlled based on the entities that are currently visible on the screen. These entities can either be generated by the Connectors/GEBs or be the entities the Connectors/GEBs attach to (i.e. connectivity). The options available in the dropdown are :

Visible Ents: This will control the visibility of all those Connectors/GEBs whose generated entities are currently visible.

Visible Parts Visible Props: These two options will control the visibility of all those Connectors/GEBs that reference even one of the visible parts or properties in their connectivity fields. This does not work with ANSAGROUPs.

Visible Parts Only Visible Props Only: These two options will control the visibility of all those Connectors/GEBs for whom all the connectivity parts or props are currently visible.

Visible Parts/Props Visible Parts/Props Only: These options allow the visibility control of all those Connectors/GEBs that have "mixed" connectivity, consisting of both parts and props.The visibility control performed by the buttons located at the bottom of the window: Show, Hide, Show Only.

BringConnectivityToVisible

Generates the button "AND_Connectivity" in the User Script Buttons menu, under the custom category "AUXILIARIES". This function gets the user in selection mode, in order to select any number of Connectors/GEB_xx or Connection Entities. On middle click it brings to visible their connectivity parts/props/includes.

The function "FourBars.bs" is removed.




GENERAL

ANSA -h The -h option is used only for : -h port@server,

Use license server "server" on port "port"

The Help with the available options is printed now only with the “-help” option.

File>Compress Fixed error that caused major instability when “compressing” CROSS SECTION Curves.

Window configuration, e.g. Active buttons, options, etc, are now saved in the ANSA.xml as soon as the “Compress” window is closed (Enter/OK).

16897

The Compress function was not able to remove unused Nodes related to Geometry. Only after deleting the related Faces the nodes could be removed. Now the Compress can handle these nodes.

17043

File> Print to File

- It was not allowed to change the 'text and axes' option when 'tiff' format was active.

- The 'tiff' format didn't respect the background color. It printed the current one and not the one specified in the print to file window.

15065

The function (Print to File) is now able to be called by a shortcut (if defined) preserving another function that was already active.

3323

The “Print-to-File” holds its own history in the File Manager. 15228

Geometry TRANSF.

The distance field was, wrongly, set to one (1) although it was set to zero (0) by the user in order to create duplicate elements (at the same position).

17354

ISOLATE > FLANGES PROXIMITY : when it had to work onto 1D gaskets would lead to abnormal exit.

MEASURE Measurement Names did not appear next to the measured entity but at the [0, 0, 0] instead.

16834

Fixed error that caused abnormal exit (or corrupted ansa file) and it was related to Measurements that were wrongly preserved although the entities they were based on were previously deleted.

Now these measurement will be also deleted.

17106

HIDDEN

Q.GRAPH

Fixed redraw problem in HIDDEN and Q.GRAPH mode for Pam-Crash “crash time step“ criterion.

The calculation of the crash time step in PAM-CRASH is affected by the value of CONTROL>TCTRL>SHELL_TIMESTEP> THICKNESS[BEND/BENDLARGE/NOBEND]. However, when this option was changed the values and the displayed elements were not directly updated for the aforementioned drawing modes.

16988



F11> Presentation Parameters

Feature Selection

The "Feature lines angle" in the F11>Presentation Parameters was updated by the value given in the Feature selection angle value (feature Area). However, if the value was changed in the F11 window did not update the value in the Feature selection ...although the selection worked with the new value ...that was not displayed in the field.

(v13.0.1)

16683

Selection tools Correctly update of the feature line selection angle when first showing the toolbar.

Feature Line: pressing the [Alt] key, in order to use the shortcut to activate/deactivate the selection tool, exited the function instead. This happened to Rigid body line elements (i.e. Nastran RBE2, Dyna Nodal rigid body, PamCrash Rbody, etc.), in TOPO>CURVEs>CONS2CV.

17575

List windows Properties/Materials: Filter line-edit

a long filter (e.g. ids separated with commas) made the list window to open with increased width. This is fixed. The selection lists in Database Browser did not have this problem.

17004

Database Browser

17672




Bolt Fixed error that caused corrupted ansa files or/and abnormal exit when the same property id was wrongly assigned to both Body and Head elements although they were of different type.

Adhesive Lines

It was not allowed to realize the connection between flanges that belong to the same ANSA_PART (same module id in P1 and P2 columns)

12521

16778

Seam Lines Fixed error that wouldn't allow the realization of OVERLAP-SHELL and OVERLAP-FEMFAT seam welds.

Y-JOINT-SHELL ( Offset row , Double row , Height ) , OVERLAP-SHELL ( Offset row , Double row ),CRIMP-WELD-SHELL ( Double Row ) :

Error caused abnormal exit in some extreme cases, such as a small step length relatively to width , height , local element length , parts distance.

Read Spots If setting the spotw_mode = XXXX then the File>Read Spots menu missed the XML option

(v13.0.2)

16713

XML: the weld direction of the Crimp Weld type was imported. 17282

CREATE DEF CNCT.->MANUAL Fixed malfunction that 'blocked' ANSA when switching from "Multiple parts per Pi" to "Single part per Pi" after selection.

Convert Fe To Adhesive (RBE3-HEXA-RBE3): Correct the connected Parts information in the resulted Connection Line.

16712

FE to Cnctn Pts (NASTRAN CWELDs) : correct the Parts assignment to connections produced by CWELDs. Two cwelds connections are merged now to one connection if corresponding cwelds share common nodes only to one side, else one connection is created for each cweld.

16824

Output The Connection's "Comment" & "Name" can be now exported as ANSA COMMENTS

14995

XML: Fixed error that occurred during XML-output of connections with seam welds containing base sheet index information:

When grouping the connections (in <connected_to> tag), some connections' connectivity was swapped (P1 and P2).

When this swap occurred, the base sheet index did not change accordingly, so when reading back, another part would appear to be the base sheet, therefore not allowing to realize again.

17274

XML: the weld direction of the Crimp Weld type was not saved in the exported file.

17282

CONNECTORs

The connector search was not able to capture the mid-side nodes of 2nd order elements.

(v13.0.2)

16882

Fixed error in case that rigid elements, as interface, were realized in areas (e.g. A hole) where rigid elements already existed.

The connector was marked as 'Ok' without having connected the representation to the rigid body on the hole.

16158



BATCH Mesh Manager

Significant improvements in Batch Mesh results by means of Quality and efficiency.

Major enhancements in Fillets treatment

Fixed error that caused abnormal exit in particular case with Box Session. 17240

Mesh Parameters > Holes Treatment

17244

Fixed error Copy Mesh Parameters from batch mesh to SHELL MESH>PARAMS:

if CFD is selected, then the target element length is now turned always to "1*initial local length" and not to CONS Resolution.

17377

Mesh parameter: "Freeze Triple bounds" was not saved in ANSA.defaults 17636

PARTs Manager

When the “Target Mass” was erased and the field remained <blank> a very small value (instead of blank or zero) was displayed in “Tree list” view for the “Target Mass” column.

Replace Wrong set contents after parts replacement. 17039



TOPO

CONS CONS > PASTE : selecting with “corner angle” tool the two sides did not result to correct application.

17200

16765

PENETRATION > Element Length: Improved “Fix” operation in order to give better result with smoother growth rate.

(v13.0.2)

17792

PENETR. : when it had to work onto 1D gaskets would lead to abnormal exit.

TO-SURF > PER AREA: fixed error that produced corrupted ANSA files.

(v13.0.2)

16785

OFFSET > COPY : when Geometry-related shells were selected (upon Macro Area) the created shells were “connected” to the Macro Area (tho the shells that initially selected).

(v13.0.2)

16841

VOLUMEs EXTRUDE > SWEEP: Fixed error that caused unaccepted mesh result. 16910

EXTRUDE > SWEEP - HEXABLOCK

Fixed error that caused abnormal exit, related to unsaved curves or line elements referred by 'sweep volume' and morphing boxes refereed by 'hexablock volume'.

16861

MESHV > DELAUNAY: Improvements to avoid swaps on boundary for better quality.

The Delaunay volume mesh takes into account the Size boxes.

Layers connection caused abnormal exit when the mesh had some highly skewed trias as well as some collapsed Cons areas. When these were fixed layers could be grown without any problem. Now the function works without exiting unexpectedly.

16739

LAYERS : correction of the messages that are printed during layers generation in the “Ansa Info” window.

16969



DECKs

Changing the Units e.g. from Millimeters to Centimeters, without activating "Scale Model dimensions" it was wrongly affected the drawing of the cross section of the beam that was scaled.

16100

NODEs PASTE: the window options are now preserved for the next application of the function.

16625

ELEMENTs Fixed error caused abnormal exit when creating line elements with the "Curve (seq.)" option.

(v.13.0.2)

16796

AUXILIARIES TRANSFORM: when applying a transformation on a set containing Properties the Connectivity of geometry nodes to FE elements gets lost. Similarly when applying the script functions CreateTransformTranslate() and GeoTranslate()

An extra argument has been added in the related script functions "Connectivity" and can be set to 1 or 0, to keep or release connectivity respectively.

No problem occurred when the set contained directly elements or nodes.

17095

MODEL CUT : Fix of model cut when plane passes through a face that belongs on volume skin.

FORCE /LOAD distribution

Distr : Fixed error that caused abnormal exit when distributing force "On Mass" and selecting SOLIDs.

Connections & Assembly

Settings Windows>Options>Settings>Connections

A new setting for the configuration of the mesh reconstruction that is performed by the FE-Repr. application, e.g. SPIDER2. If the checkbox is enabled the mesh parameters, i.e. mesh size, feature line detection, etc, through the “Mesh Parameters” window (MESH>SHELL MESH>PARAM.) will be used, otherwise internal default values will be taken into account. Thus, if configuration of mesh parameters is required, activate the option and proceed to the configuration via the PARAM. Function.

Currently the new setting is used only by the SPIDER2 FE-Representation.

Create Connections

TOPO & MESH>WELD SPOTs> DEF. CNCTN>MANUAL

The “Edges” selection option is supported for : Multiple Connection Points: and :Connection Curves” creation.

Moreover, for “Edges” and “Perimeters” selection, the 'curve' can be formed either on the selected line or in the “middle” in case of curve pair selection. supports edges.

When middle curve preview can not be produced a temporary warning message is shown. Middle curve preview is not produced when only one perimeter or line edges are selected or when the selected edges or perimeters have too different lengths.

!!! Even though for the selection of edges, box selection is available, it should be preferred for easier deselection rather than selection. The angle of "feature line window" is suggested to be used to define the preview curves.

13633

The CONVERT function is now available also in MESH>WELD SPOTs 5011

TOPO/MESH >WELD SPOTs>CONVERT> FE to Seamline

CWELDs,only ALIGN type, can be converted to seamline connections.



TOPO/MESH >WELD SPOTs>CONVERT> FE to Cnctn Pts

The created Connection Points haveas Comment the PID information of the elements to were converted.

FE- Representations

RBE3- In case the “Keep All Branches” = OFF

and (by a new internal check) the realization of the RBE3 is done as if the “Keep All Branches” = ON so as to avoid FATAL Errors during the solution.

16288

Bolts Interfaces> Zones: “Outer”

New option has been added to attach only to the outer nodes of the zone.

9644

Attach mid-nodes of 2nd order elements when applying Bolt Connections. 7871

11398

SpotWeld Point/Line

NASTRAN CWELD

For the type ELPAT a new option 'Create Piercing Points GA,GB' is added. When enabled the created CWELD is defined by GA,GB and not GS.

This option is not available for Gumdrops, as without GS no mass could be defined with cweld.

15715

SPIDER

"Compatible Holes" option added. When this is enabled, the perimeters of the created holes are aligned to the closest perimeter of all faces were the spider-hole s are created.

7105

SPIDER2

"Dist From Perim":

set the least desired distance between bounds ( perimeters and features ) and outer zone of the spider

"Allow Violation of perimeter" -- "Allow Violation of feature"

if the spider lies on a narrow flange, and there is not enough space for the hole & zones, you may explicitly choose to violate the distance criterion from the perimeter, feature, or both bound types.

"Move Up To"

specify the max distance that the connection may move to find the best position according to the criteria above. The biggest this value is, the more time it takes to find the best position. If remains BLANK, it is allowed to move up to the Search-Distance.

!!! Note, that in order for connection manager to respect a certain (say 5-degree) feature angle, so that reconstruct doesn't break these features, click the [Windows->Settings->Connection->Use Current Mesh Parameter Values.] and make the proper customization in the “Mesh Parameters” window

14992

12483



before the connection Apply.

Otherwise, connection manager will use internal default mesh parameter values.

Adhesive Lines

CONTACT

A Tie Contact is created.

The slave set contains nodes collected from P1 part according to a detection distance and the master set contains properties from elements from P2 part found in a search distance.

The Width [W] of the connection is used as the detection distance. If width is 0.0, the slave set will contain all nodes of all elements from P1 found in a search distance.

Contact ID:

-If "Contact ID" is given and corresponds to a valid contact, the given contact is used as a template and one new contact will be created by copying the template.

-If "Contact ID" is not given, Connection Manager will look for a contact whose master set contains the shell properties needed.

If no matching contact can be found, a new will be created.

In case "Contact ID" is not given, the search distance is used as POS_TOLER in the TIE card.

14369

Adhesive Faces

RBE3 : new representation.

The REFGRID Nodes of RBE3s are searched from connection face to part P1 within search distance. For every REFGRID Node the other nodes are searched to part P2 within search distance.

If RBE3 diameter is BLANK or ZERO, only the nodes of nearest, to the REFGRID node, shell are assigned to RBE3. Else, all nodes from projection point ( of Ref Node to nearest shell ) within Rbe3 diameter are assigned to Rbe3 too.

15687

HEXA-CONTACT , COHESIVE-CONTACT

"Create Single Contact" option is added.

15330

Seam Lines

NASTRAN CWELD: new representation.

Creates CWELD type "ALIGN" for Seamlines

15572

SHELL-CONTACT : Seam lines new representation realization using shell plus tied contact

W is considered as the thickness of the the seam-weld shells.The shells are not pasted with the connected parts.No reconstruction on underlying surfaces.Interfacing achieved using tied contact (shell edge2surface + offset option).The projection method will always be normal projection from the connection curve to the 2 parts, regardless of feature lines around. This means that when realizing e.g. a T-weld, the weld-shells will not be necessarily vertically projected to the flange, neither necessarily attached to the feature line. It will all depend on the connection curve positioning.

8887



Y-JOINT-SHELL:

“Keep Adjusted Shells” new option. If it is enabled the shells that correspond to the "height" adjustment on Y-JOINT-SHELL are not erased. Therefore a blue bound between the weld shells and the secondary sheet shells is defined.

15187

CONNECTORs

Search methods PassThrough option has been added.

ResultsFromSet option has been removed; it can be achieved with Connectivity = SET and Search Method = PassThrough



BATCH Mesh Manager

Mesh Parameters

Fillets:

Chamfer treatment

"Do not join perimeters created from split treatment" is used for both, fillets and chamfers.

UTIL

The projections are now performed on each different part or pid instead of finding the closest one

UTIL

A pull down menu gives access to the function list.

Each function is applied onto selected entities. The application on the “Visible” entities has been removed.

Once a function has been selected there is still a chance to use a different one as this can be defined in the “Utilities Parameters” window by the Mode option:



RESHAPE: Preview is available when the function applied onto FE-mesh 15925

ELEMENTs WRAP > [Variable length] : now it takes into account the Size Boxes 14840

PENETRATION

Solid Elements have thickness only for current Deck modules LS-DYNA and ABAQUS. In all other decks, property thickness penetration between shells and solids is detected only if the solid gets “inside” the shell's thickness.

16559

VOLUMEs Volume Mesh Generators are now able to mesh Volumes with more than 1000 sub-volumes.

13272

MAP > Thin Parts :

New function to be applied onto curved thin parts. The created map mesh orientation will follow the shape of the master shells and will be perpendicular on them.

MAP : the selection order for the straight transition has been changed. Thus, the path of transition is given just after the selection of the master and slave surfaces and not at the end.

14333

EXTRUDE>OFFSET

The offset distance value can be specified from the screen, i.e by picking two positions.

15242

EXTRUDE : the created solids have now the same number of pids (instead of only one pid) as the root shells. Thus, if the selection of the root shells contain two properties, then two solid properties will be created.

16516

Mesh Parameters

Holes Treatment

Specify the hole's Node Number also by giving :

• the hole's perimeter element length (L0), or

• a zone's perimeter element length (maximal 15 zones, L1-L15),

In addition the node number can be defined as :

• a product of the target element length (*L), or

• the minimum element length (*Lmin).

The ansa_mpar file is also changed in order to support the new features (N=, L0=, L1=, L2=, etc.).



Mesh Parameters

All parameters that define the target length are now written in the ansa_mpar file (from SHELL MESH>PARAM.).

The new entries are written under the "element-length" and are:

a) target_element_length_radio (accepts: Specified, Average, Free)

b) target_element_length_factor (accepts: a float number > 0)

c) target_element_length_param (accepts: init_average_len, init_local_len)

ELEMENT UTIL>Change Type>1-D Entities:

Changing from line elements with no orientation (e.g. TRUSS) to elements that require orientation (e.g. BEAM) does not create non-accepted elements (i.e. collinear orientation axis) but elements with default orientation. Mind, however, to verify the result.

16092

AUXILIARIES BOLT: Added option to attach only to the outer nodes of the zone.

BOLT : The bolt axis is corrected to pass through the center of the smallest hole.

DB Browser – Lists

Properties/ Materials

Materials' Mapping List is now available also from "MATs SYNC" window of property list.

15216

Curves / Tables

Improved performance when reading huge files with tabular data (e.g. with more than 120000 lines)

Respecting of blank spaces when used as separator of columns. However, if other separator is used (e.g. colon) no blank spaces should exist before or after the separator.

15083 (ii-iii)



SAFETY FMVSS 201U

Target points detection - generation for all the vehicle's interior components.

The FMVSS Tool is used for the calculation of the target points and the positioning of the FMH (Free Motion Headform) for the simulation of the occupant protection in interior impact laboratory test according to the FMVSS 201U standard

FMVSS 201U Interface separated in three tabs :

Target Points - Positioning - Manual Operations.

Target Points: The user has to feed the tool with a number of sets (Vehicle Components Set) and a number of points (Seating Reference Points), in order to calculate the target points. With the Get Target Points ANSA calculates the needed planes and derives the characteristic curves and the target points. At the same time that approach angles for each point is automatically calculated and are set in the appropriate fields in the Positioning tab. The created planes, curves and points are stored in sets with the prefix FMVSS201U. With the Undo All the user deletes all the above.

Positioning: This tab is used to position the FMH to the target points according the FMVSS 201U regulation.

Manual Operations: This tab is used to manually position the FMH.



Pedestrian

The “Reference Lines” creation includes both EURONCAP & EC Reg. regulations

New Buttons :

WAD Line : for creation of customized WAD linesConv2Beams : for converting curves to beams

Moreover, 3d-points are create at the intersections of translated side lines with lateral lines.

Target Points:

Distance : defines the minimum desired distance between the critical points that will be detected in each area.

Rotate Dummy / Rotate Dummy Part

'Total Rotation Angle' field became editable. Dummy part or Dummy is moved at the specified position after OK or Enter is pressed.

All Safety tools can be applied onto geometry, i.e FACEs.

CHECK PENETRATION & CONTACTS : Solid Elements have thickness only in LS-DYNA and ABAQUS. In all other decks, property thickness penetration between shells and solids is detected only if the solid gets “inside” the shell's thickness.

15967

ELEMENTs CWELDs > ELPAT / PARTPAT.

The Piercing Points GA and GB, can be created onto the connected patches by activating the option of the dialog box that pops up.

PARTPAT: Allow multiple CWELD definitions by selecting multiple GS nodes.

ELPAT: when the “Create Piercing Points GA, GB” is enabled and NOT GS is picked (middlemouse is used to skip GS selection) the CWELD is created without GS but only with the GA and GB piercing points.

15715

SOL200 Topology (TOPVAR), Topography (BEADVAR), Topometry (TOMVAR) are supported.

CHECK CWELD

A new errors detection function is added to identify :

“invalid projections”,

“invalid agnle between patches”,

“not shell nodes used as GA,GB in type ALIGN”,

GENERAL

DB Browser PROPERTIES, CONNECTORS, GEN BUILDERS: fix for edit cards, modify and display for fields: PRESERVE, FORCE, SUBOPTION

15835

While the Database Browser was active caused long delay on switching modules (e.g. Mesh to Decks) in big files.

15438

It is now allowed the modification of FROZEN_ID, FROZEN_DELETE on Curves and Tables (e.g. LS-DYNA *DEFINE_TABLE) within the Database Browser List.

12462



FOCUS ISOLATE>Single : used to keep also 1-D elements, i.e Bars, Rbodies, etc.

14132

ISOLATE>BAFFLES : Fixed error caused unexpected exit on WindowsXP platform.

GUI

Settings

When starting ANSA with the "-i" option and giving a CAD file (i.e vdafs, step, iges) the menu buttons on top of the GUI are "messed-up" and some lost their labels.

15012

Unnecessary warning messages were printed during buttons relocation.

15011

SHADOW In particular cases the Pause/Break does not halt the shading process. 16102

Pull down menus of buttons

On Windows platforms (XP an Vista) the mouse-release event for pull-downs of buttons did not activated the button's default option and the pull down menu remained visible with no option selected.

16174



TASK Manager

Surf.Wrap Adding the "Surf.Wrap" item, Editing it and pressing Cancel/Esc in the window caused abnormal exit.

15022

Optimization task Could not export ABAQUS explicit in -nogui mode in an optimization task

15259

Connections Wrong message at 1st run of TM regarding Connection Status:

Spider & Bolts which support the 'Allow Single Part' feature, failed to pass the task-manager check.

15303

TOSCA Hitting Cancel/Esc did not discard the creation of a TOSCA task item.

15929

Several fixes in TOSCA Task creation and editing.

Model Checks / Fixes

ABAQUS : Check>Fastener

Now the check is performed for fasteners that belong to the task.

Convert from Model

Contacts of spotwelds are not merged into the Task. 12318




Modifications of connections' values from connection manager, database browser or script became faster.

15037

15038

“Erase FE” removed not only the FE-Repr. Properties but also all the ones that were created as “Copy” (manually) of them.

16272

Realized Connections in old ansa files (older or equal to v12.0.2) appear as having status 'blank' instead of 'Ok' when open these files in v13.0.1

16277

Having the Connection manager docked, option "Edit Connection" did not work.

15965

ANSA.defaults with more than 100 entries in the mapping table thick__spw_diam caused abnormal exit in launching ANSA.

The maximum length of the array changed from 80 to 202.

16137

External Assembler

When the connection with External Assembler is made, the “Status” became <blank> and the “Error Class” became "CUSTOM FE".

15448

Connections Selection Assistant

Select spots of “Visible Props.” did not work on solid properties. 16593

Gumdrops RBE3-HEXA-RBE3 : misleading message "Internal error Validating Gumdrop" was printed although the connection was realized.

15560

Adhesive Lines

RBE3 diameter did not work for adhesive lines with regular distribution 15861

Hemming FOLDING : In many cases even though elements were successfully folded, the RBE3-HEXAs were failed. Algorithm that creates HEXAs on hemming is now much less error prone.

15683

Seam Lines Y-JOINT SHELL: Fix Y-Joint height adjustment so not to shrink the heat affected zones (HAZ). The HAZ width defined is now respected.

15309

SpotWeld Points/Lines

RADIOSS WELD: 'Use thickness to PID Map' option did not work when called a script function. This error first appeared in v12.1.5

15621

SPIDER2: Fixed error that caused abnormal exit on realization. 15756

NASTRAN CWELD: Fixed error that made unable the realization of CWELDS type ELPAT (no space for the spotweld area).

During the Cweld realization the elements to be created are checked if they satisfy the Nastran projection criteria. The Diameter within the PWELD is taken into account for this check. Therefore, for ELPAT & PARTPAT welds that are applied with a non existing PWELD-ID, this PWELD that will be auto-created, will have D (Diam) = 0, even though the connections may have D>0. If the PWELD diameter is modified later, the CHECK>CWELDs has to be performed manually.

Applying CWELDs with an existing PWELD ID (or with the PWELD field blank) the CWELDs to be created will be checked with the current diameter, thus they will fail if there is no space for the spotweld's area.

16190



Bolts Applying Bolt (with current Deck module = LS-Dyna) with “Body Type” = RBE2 , the setting “Split In” >1 , the fix rigid dependency that is automatically done (to avoid dependency conflicts due to Rigid Parts, etc.) created some unnecessary *Constrained_Extra_Nodes.

Connection manager did not drill bolt holes if the holes were quite close to the boundaries.

This margin from the bounds has been decreased, and holes can be drilled now very close to the boundaries.

7210

Check CONNECTIONS: Fixed error that caused abnormal exit during check connections

16297

Convert Connections : from Spotweld Points to WeldLine did not found common connectivity. In v1301.

16200

Fe To Adhesive : abnormal exit when converting Pam-Crash LLINK elements( on Ansa 64-bit).

15342

CONNECTORs

For current Deck module Pam-Crash, the “Interface-i” RBE2 creates now Rbody type 0 with the exact definition of Pam Crash. The NCOG is auto-defined by the Apply and not during the output to Pam-Crash.

10129



BATCH Mesh Manager

Problem when changing the 'Fill' option to 'Spot' in Holes treatment; the change was not applied.

15075

When saving the layer parameters the file manager did not automatically fill the *.ansa_lpar in the filename.

15276

Save Session did not save parts correctly in the case where the scenario was PID based. 15071

Save Scenario: The File Manager did not open and the saving failed, in case of non-existent DM path.

15271

Fixed abnormal exit in batch meshing of particular case. 15158

Some FE shells were not highlighted from the batch mesh Parts window. 16425

Draw Sessions did not colored the parts of the session if

• FE elements (not geometry) was loaded in a session and

• were selected as PARTS/GROUPS

16428

PARTs Manager

Save Part Boundaries or Fasteners which belonged to a part were not saved correctly in the new ANSA file.



TOPO

CONS PROJECT : double projection of faces. Fixed the problem , caused ONLY when the Feature are selection tool is activated and the selection is done by simple click on the CONS - not by box selection, and created unaccepted projection.

16055

PASTE: Problem with the selection of joined CONS which didn't have hot points on its boundaries; the selection continued to the adjacent double (yellow) CONS.

15324

FILL HOLE: if the "Convert point to connection point" was activated without activating the "Make point at center hole" flag no connections were created.

Now both options work independently to each other.

15250

FACEs MIDDLE>MULTI: Property assignment of new middle faces was wrong in a specific case, when exiting and re-entering the function to continue.

15629-vi

MIDDLE>MULTI: Fixed error that caused abnormal exit when using Auto & Trim manual on Unix HP UX11

16026

SURFs COONS and SURFs>SWEEP/GLIDE:

when selecting an element edge of FE-model mesh ANSA terminated unexpectedly.

15411

6873

A.SPACING > [CFD] : Fixed error that caused abnormal exit on a particular case.

16191

GRIDs A.PASTE

When using "Selected Nodes" and activating "Project on Geometry", there was no projection. The projection performed only with "Selected Elements".

Having selected "geometry Pos", the nodes were moved to the “average position” and vice versa..

Malfunction of the "preserve ids" option has been also fixed.

15081

ELEMENTS EXTRUDE > SWEEP / GLIDE: fixed error that caused abnormal exit. 15123

SPLIT>[SOLIDS] did not allow the splitting of solids when the whole database was visible. Function worked only if remained visible an isolated small area around the solids to split.

15987

WRAP > [Variable length] if implying no contact among any PID (Contact Groups = 0), produced elements smaller than minimum length. Regardless of the specified length range ANSA refined down to 1. It checks now the “Min length” of each PID instead.

16169

VOLUMEs MAP : failed to remesh after cutting one macro but leave the same number of elements.

16278

MAP : correct misleading warning message (“Incompatible Master slave combination”) that was printed although the problem of the mesh generation was related to an existing volume definition.

16341

MAP: fixed error that caused heavily distorted solid elements. 15209

MAP : a message is printed if surfaces belongs to already defined 16225



volumes.

MAP : fixed error that produced wrong and unaccepted mesh result when the function was applied onto 2nd order mesh.

16240

MAP: fixed error that led to abnormal exit on particular cases. Appeared only for 32bit ANSA v1301.

15318

MAP - Volume Remeshing :didn't work on copied volume definition, e.g. created by Geometry>TRANSF.>Copy. All the surfaces of the copied map-volume were marked as master.

15777

EXTRUDE > TRANSLATE : fixed error that caused abnormal exit related to Faces' and solid's facets selection using the Feature area.

15439

EXTRUDE>OFFSET : fixed error that caused unexpected termination. 16238

15104

Output Parameters window > Miscellaneous > Thickness

When exporting element thickness (Output elements' thickness) enabling the “using properties grouped by element's thickness” an invalid property with 0 thickness was created.

15940

ABAQUS / PAM-CRASH : fixed error that caused export of multiple elements with same ids when MULTIPLE PROPERTIES were assigned on Macro Areas.

16281

Splitting line elements by the TOPO/MESH>HOT-POINTs>PARAM.and INSERT function was not possible

15752

15868

GRIDs/NODEs PASTE>Auto

When using "Selected Nodes" and activating "Project on Geometry", there was no projection. The projection performed only with "Selected Elements".

Having selected "geometry Pos", the nodes were moved to the “average position” and vice versa..

Malfunction of the "preserve ids" option has been also fixed.

15081

ELEMENTs UTIL> Change order : from 1st to 2nd order elements conversion left unconnected nodes

15451

UTIL > Renumber : having enabled the “Macro Area” option in the “Feature Selection” and using 'box selection' was selecting twice the elements and led to invalid renumbering. The error might cause corrupted files after saving.

16564

SET Modify Contents: fixed error related to selections of property sub-categories and unwanted removal of all properties that were contained in the set.

15426

Fixed error regarding highlighting of sets after filtering. Sets that did not match the filtering and did not selected in the list were (wrongly) highlighted as well.

15325

MODEL CUT When rotating a cutting plane from its Z-Axis using MV.FREE, pressing Esc didn't return it to its original location (appeared in v12.1.6)

15915

Impactor Impactor Positioner caused abnormal exit when a second vehicle model is imported as an impactor

16020


Entities specified as excluded in sets were not interpreted properly from the check>contacts function. E.g. if the set is used in a tied contact the excluded nodes (DELETED) of the slave set were still considered for the projection validity although they should not.

15605



AUXILIARIES CONTACT>FLANGES : significant improvement of the function's results especially for contact detection onto solids' facets.

11709

SAFETY K JOINT - Rotate Dummy part

Although the K_JOINT type was changed, e.g. from spherical to revolute, the Rotate Dummy Part recognized the K_JOINT still as the previous type.

16107

Fixed error that caused wrong interpretation of the K_RBODY information, stored as comments, in the imported deck file. The case was related to definition of K_RBODY with ANSA_PARTs.

Pedestrian > Reference Lines:

- Fixed error at bumper reference lines creation.

- Smooth translated rear bonnet reference line's corners

16152



NASTRAN

15646

D. UTIL D.INFO:

Fixed errors that caused improper calculation for NSM

- In order to calculate the NSM mass in the Deck Info, the user had to activate the NSM visibility, although the option "Apply on Whole DB" was selected.

- If the NSM Set was defined as a combination of two or more NSM Sets (NSMADD) then the NSM mass value was ignored at all.

D.INFO :

When NSM or NSML was defined on a property set, the NS mass was always computed in D.INFO for all included types (e.g. PBAR, PSHEL ) that might contained in the used set, although only one particular type was chosen in the NSM card e.g. TYPE=PBAR.

10986

D.INFO:

Fixed problem in calculation of the COG of CONM2 elements with offset values.

If a mass element (CONM2) was applied on “Set of nodes” is transformed through the X,Y,Z offset distance values, the D.Info did not respect the offset for the calculation of COG.

GENERAL

A new Graphic User Interface with many new menu and layout customization options:

a short description of the new layout:

1.Main pull down menus

9.Database Browser

10.Status Bar

6.General Buttons

2.Toolbars

3.Module Buttons

4.Module Buttons Group

5.Hidden Buttons pop-up

7.Ansa Info8.Command Line

Hidden Window



Launching When ANSA v13.0.1 is launched searches (to read) the ANSA.defaults , ANSA.xml and ANSA_TRANSL within the folder:

for unix

/home/user/.BETA/ANSA/version_13.0.1/

instead of the user's home directory

for windows

C:\Documents and Settings\user\.BETA\ANSA\version_13.0.1\

that will be automatically created the first time ANSA will be launched.

Apart from the .BETA folder ANSA.defaults and ANSA_TRANSL are read in also from the ANSA_HOME and the current directory.

All settings that used to be saved within the ANSA.defaults that were related to user layout (buttons, colors, fonts, etc) are obsolete since all these settings are now stored within the ANSA.xml

The ANSA.xml file has all the user settings regarding the buttons location, menus configuration, colors, fonts, window style, windows size and location, filters, list windows configuration. The ANSA.defaults file hosts all the functions' configuration like mesh parameters, morphing, topology settings, etc.

ANSA.xml can imported in an open ANSA or can be auto-read by any location using the -xml starting option.

Moreover, you can start ANSA with the -gui option and as a second option give a <name> that corresponds to name.defaults and name.xml, e.g.

ansa.sh -gui cfd

will start ANSA that will read the cfd.defaults and cfd.xml which are placed into the /home/user/.BETA/ANSA/version_13.0.1/

or the ANSA_HOME directory.

Windows All List windows and Module Buttons windows can be docked, e.g. on left/right or bottom side of the main ANSA window in order to have more clear graphic area.

The windows can be tabbed in other docked windows.

A preview is given when a window is docked or placed as tab – using drag and drop.

Expand the size of a window by moving the mouse towards the side to be expanded holding down the “middle mouse button” and the “Shift” key. This is not available for tree-form list windows, i.e SETs

Click with middle mouse on the title bar of a floating window in order to “roll it up” . (the window is minimized to its title bar)

Columns in List windows can be added by using the new tool List Fields that provides all the edit card's fields of the listed items.

Menus The bottom menu called General Buttons is available in any Module Menu in order to reduce menu changes. All General buttons can be used despite the currently active Module. For instance the REALIZE button that launches the Connection Manager is available also when a Deck menu is active.

All Module Menus (TOPO, MESH, MORPH, DECKs, etc.) as well as the General Buttons can be docked or tabbed.

Buttons of each Group of Module buttons can be easily placed in a position or in the Hidden window by drag and drop. The Hidden buttons pop-up window easily accessed by the arrow next to the Group's name.



The Hidden window opens by right-click onto Module Buttons group label. Functions of an open Hidden window can be used in any Module menu, e.g. The Hidden window of MESH>SHELL MESH can be used while the Deck>NASTRAN Module is active.

A Group of buttons in each menu (Module/General) may be removed or added group

User Menu A custom made menu can be created by “drag and drop” Module buttons, Group of buttons from any module, including the buttons that are created by script. User Menu and Groups of buttons within it, can be given any custom name.

To create such a menu go to Modules>Create Menu. The edit mode is activated ; during this mode only custom user menu definition is allowed.

In the field next to the Add Group button enter an appropriate name for the first group of functions that is going to be created, and press Add Group.

The Deck Mode specifies the deck module that can be used as source of deck buttons.

The Draw mode specifies the style of the displayed Faces/Macro Areas.

Using drag and drop with the middle mouse button, pick buttons from any module buttons group, to place them in the group of the User Menu. A whole module buttons group can be placed in the User Menu, by picking it with the middle mouse button from the label of the group.

Tooltip balloons indicate the origin path of the button that is placed in the User Menu.

Delete a button from a group by pressing the Ctrl key and the right click on the button. Once a group is empty from buttons the user can delete it, by clicking with the right mouse button onto its label while pressing the Ctrl key.

Press Finished to confirm the custom menu definition. The new menu is available as a Module Buttons menu.

To edit an already created user defined menu, one have to activate it and then by right clicking on its title bar select 'Edit Mode'. To delete a user defined menu, right clicking on its title bar and select 'Delete Menu'.



Shortcuts Any button can be assigned to a keyboard shortcut combination with Shift, Ctrl or Alt keys

Buttons defined by scripts can be also called by a shortcut key.

The toggle buttons (switch) of the Selection and Drawing modes (ENT, PID, MID, ..) can be changed (switch between options) using a shortcut.

Shortcuts are defined by the Windows>Options>GUI Settings>Buttons Manager

140

Windows > Options

The Windows>Options enable the Options - Buttons Manager window that gives access to “Functional preferences” and “Menu/Layout configuration”.

The options that are related to Functions preferences are listed under the Settings section (mainly hosts the former SETTINGS>SETTINGS menu). They are saved in ANSA.defaults

The options that are related to menu, layout and user interface customization are listed under the GUI Settings. They are saved in ANSA.xml.



GUI Settings

Menus and Windows:

- specify the Window style

- customize the number of Rows and Columns for buttons for the Module Buttons , General Buttons and User Script buttons menus.

- configure the drawing (size and position) of the Axes for the Global Coordinate system

- Enable/disable Tooltips for Module buttons and Docking for windows.

Colors:

- customize colors and enable Gradient style for the main drawing area

- choose colors for the Layout (buttons, windows, menus, etc)

- handle Front and Back color for Faces, elements, etc (ENT drawing mode)

- enable the different color between lines in List windows.

Fonts:

- choose font type and size for OpenGL , Windows and Menus

Toolbar Manager:

- handle visibility, icons, labels, etc of buttons in toolbar

Buttons Manager:

- control visibility for main toolbar functions

- customize the default action of the drop menu (the first option of the menu which is also enabled with single click on the button)

- define Shortcut keys for functions



- assign icons for buttons

- modify button's tooltip and label

!!! with Ctrl+middle_click onto a button opens the Buttons Manager directly for this button configuration.

Due to the fact that all user preferences regarding layout, menus, function pull down menus options, etc are stored in ANSA.xml, these particular settings are obsolete from older ANSA.defaults (where they used to be stored).

SELECTIONS Area selection : new window with icon-buttons that can be docked on the toolbar menu.

new selection types:

Macro Area : the entire Macro Area is selected with single click. Box selection selects Macro Areas as well.

PID Region : single click selects elements that define a region of the currently visible and connected shells of the same property. The selection stops at blue bounds (common edge for more than two elements).

Feature Line : new window with icon-buttons that can be docked on the toolbar menu.

PID Neighbs : new selection type that with single click selects line elements (e.g. beams) that are currently visible and connected.

The Feature Area selection has been added in several functions like the TOPO>FACEs>[SET PID] , the Geometry>DELETE or the DECK>ELEMENTs>DELETE.

784

Exiting Codes

ANSA returns the following exiting codes:

0 : normal exit

-1 : licensing related error (no available credits, communication error, etc)

other than 0 or -1 : abnormal exit



Database Browser

Database Browser

Windows>Database

A new database browser window that can be docked and remain active along with any function.

The browser provides a tree formed list and list management windows for all entities of the loaded database controlling also their visibility as it used by the F12 window.

The Include Manager and the applied Advanced Filters (of any list) can be accessed via the Database function.

As soon as the user selects one group of entities, the respective Selection window appears, which can also be docked. In order to open the Selection list for the first time double click on the entity in the tree-form list.

Moreover, the list of Reference entities appear as Tab in the Database browser.

Right click on a group of entities provides a drop menu with on-screen control functions (Show, Hide, Show Only) as well as to Open or Open in New Tab in order to launch a list with these entities.

Entities visibility control

The visibility of all entities by means of their drawing is now controlled by the Database browser. The “Deck Parameters” window that was launched by the F12 is removed. The F12 key now launches the Browser if this is not already open.

The display control is achieved by the check boxes under the Visible column.

Right click on the header label [Visible] activates the menu with the options All, None, Invert, Lock

The check box of the Group of entities (e.g. ELEMENTs) controls all “child” items. It also “remembers” the status of the 'child' items since the last time.

If there is at least one 'child' item not enabled the Group's check box is faded.

Filter window

In the Filters window all the applied filters that have been produced from the advanced filtering in the lists, are saved and remain available for future use and editing.

The filters are categorized according to the type of entity that had been applied to. In this window a right click menu is available either for a group of filters or for each filter separately. In this menu, visibility commands are available, edit and delete actions, plus evaluation actions.

By selecting 'Evaluate', 'Re-Evaluate' and 'Evaluate All', you can apply the filters and see how many entities satisfy its rules.

All the filters in the Filters window are saved when ANSA quits in the ANSA.xml file, and are available for future use.

Clicking on a filter opens the respective list (displayed in the Selection window).

By clicking on a filter and dragging it, for example on an include, all entities that satisfy this filter are dragged and dropped into the include.

The right click drop menu for Filters:

Multiple selections are also allowed.

The Filters of a group can be edited with right click onto the group name.



Selection list window

Within the Selection list all common visibility and selection options are available.

Right click in the list opens a menu with the functions that can be applied on the listed items. These options can be available as buttons in the lower part of the window while they can also be hidden.

History arrow-buttons (Go back - Go forward) switch between selections that were made within the Database, the Includes, the Filters or the Reference lists.

Right click on the column's label enables a menu with on-screen isolation control [Show, Hide, Show Only] for referenced entities, open list options [Open, Open in New Tab] and direct quick modification <modify>.

For example, when the Material ID has been added as a column in the Property list, the right click onto the MID label (column's header) allows the visibility control of the respective materials referenced by the selected properties.

LISTs In the Selection window of the Database Browser as well as in all LIST windows is now possible to add columns based on the edit cards of the listed items using a new tool that is launched by the option List fields. Activate the respective check boxes and the list. A proper switch exists in order to change the type of the listed keywords, if exist any different. Moreover, auto-completion for the available fields is available in the <add new column> feature.

The simple Filter edit line hosts the used Filters History (including both simple and Advanced filters).

The New and Delete options are available.

The lower and upper buttons or check-boxes of the list windows can be appear or disappear on the window. This is controlled by the arrow on the left side of the window.



Filter in Lists

For the Database Browser's Selection list and all LIST windows:

- The filter field hosts the history of the used simple filters and advanced filters.

- user is able to filter based on the field of the listed items' edit cards. Auto-completion/suggestion of the field label is provided.

- filter type "Expression" is now available also for the simple filter. Type "Expression:" in the simple filter line followed by an expression (for example in a property card check if the MID1 is greater than 2: @MID1@>2, or reference a field from another card: @MID1@->@NU@==0.3 etc.).

- The user may omit to type "Expression:" and type right away an expression. The filter will be interpreted as an expression as long as it starts with a @ and the first field (the value between the first two @) is one of the columns in the list.



Modify massive modifications can be performed:

• quick <modify> directly on a field that appears as a column; right click on the field's label header and type the new value that will be applied to the field of the selected items

• Advanced Modify: right click in the list and choose the Modify option (former EFM>Modify tool) to enable the dialog box for the modification of more that one fields in one shot.

The expressions and language of the EFM tool (Edit-Filtering-Modify) , like $, COUNTER are still valid.

Modify can handle Name and Comment fields (strings) with no need to close the string in double quotes " " in case of simple cases, e.g. substitute all the name with a new name or add a comment in a blank field. In complicated cases where special characters are used the double quotes are needed.

If any entity failed the modification process, an option is given to have a list shown with these entities.

The box that hosts the fields “to be modified” can store the input fields. Moreover, is able to auto-complete the name or suggest possible options of the field, for easier input.

The last used “Modify Rules” for each entity type are preserved during the ANSA session and are saved in the ANSA.xml for future use.



Filtering Advance filters:

New interface:

The box that hosts the field that is used for the filtering stores previously used fields and auto-completes the name of the input field (providing also potential field labels)

While the Apply button isolates in the List only the items that fulfill the given filtering criteria the Select button selects only these items without removing the other items from the List.

New filtering types:

- "Expression": type an expression using the EFM language, for example in a property card check if the MID1 is greater than 2: @MID1@>2, or reference a field from another card: @MID1@->@NU@==0.3 etc.

- "use filter". A filter is able to use another filter. Select two or more existing filters and create a new filter that uses the selected filters, either matching All or Any of them. Mind that when a filter references a filter that is absent, the check always returns true (pass) for the absent filter.

The name of an Advanced filter is automatically added in the history of the used filters accessed by the simple filter of List.



Besides the method through the Filter Rules and Modify Rules windows there is the option to choose the fields to be filtered or modified through the edit card of the listed entities that accessed by the “Open Card” button.

The “edit” card is available only for the type but not for the group, i.e for Shell Properties or Beam Properties but Not for All Properties.

The card of the respective (selected) entities opens. Enable the label of the field and type the filtering or modification expression and thus perform the filtering/modification directly in this card, without creating filtering or modification rules by adding fields.

STEP : Improved interpretation to STEP format. Parts Hierarchy, Property Name and Property Thickness are supported. Properties (PID) are translated into Layers.

IGES : Property Thickness can be exported.



File> Compress

The function includes the former FILE>COMPRESS and the DECK>CLEAR capabilities.

Provides a preview of detected unused entities in a tree list for ALL entities: F.E. , Geometry, ANSA Parts/Groups.

The activated check boxes for each entity enable their deletion. The check box for the “parent” level entity eg. F.E. Affects all the “child” items.

The [ Details ] button enables the preview of the detected unused entities and allows control and further selection/deselection of the “entities that will be removed”.

The “In List” column shows the number of the detected items that could be removed. The “To Compress” column shows the number of entities that will be finally removed.

974



Double left click on the number to open a list of these entities. They appear marked in this list; Deselect the ones that should not be removed and press OK. Only the marked items will be removed.

When the check box Delete by step is enabled then the removal of some entities is done only if some other is removed before.e.g. the removal of the Load Curves that are referenced by unused Materials is done in a next step, after the Materials' removal.

File Manager Filters for Directories and Files are available where Regular expressions can be used.

Display F11 : Quality Criteria – Presentation parameters window

Detail on Demand : This display control feature has been added in the Presentation Parameters tab of the F11 window.

Provides a gradual increase of detail for the model, which will depend on the current view. Such a “detail on demand” effect can be obtained by adjusting the respective regulator.

The more the user zooms in, the more details of the model come to visible, leading in a more detailed view of the model.

The detail on demand effect affects, first of all the visibility of the mesh in a model. By zooming out, the wire is lost equivalently to the view with the WIRE flag off. In this case in order to indicate the existence of mesh on Macro Areas, small dot are displayed in the middle of the shells.

The righter the regulator is, the more intense is the effect, which means that less zoom out is needed for the details disappear.



Graph Parameters

The settings in this tab control the color view modes:

EL.THICK , EL.NSM, EL.PRESS , EL.TEMP , C.THICK , M.SCALE, QGRAPH , SGRAPH

Besides the Q.Graph and S.Graph sections that refer to the respective color view modes, generally:

Color Bar Limits

select the limits of the color bar, by choosing one of the following three options:

Whole DB: Auto adjust range from all shell elements of the Database

Visible: Auto adjust range from Visible shell elements only

User min-max: Specify user defined min and max values in the two activated fields

Ranges defined min-max: used only for the Q.GRAPH color view mode

Color Bar Colors

select the way the color bar will be configured, by choosing one of the following two options:

Palette: Specify the number of classes (colors). Each color can be configured by pressing on the sample square.

Unique color: Assign a unique color for each class of thickness.

Use unique color for each range : used only for the Q.GRAPH color mode

The “Color Bar Limits” and the “Color Bar Colors” options can be combined according the user's needs.



Color View modes

SGRAPH: Separation Graph color view mode

This new color view mode can be used for comparisons between two FE meshes or between a FE mesh and a geometry.

Having in the current database two FE models with a certain mesh, or a geometry model and a FE one, activate the SGRAPH view mode to compare them.

The shell elements of the FE mesh are colored according to their distance from the geometry.

The distance can be calculated based on the selected option inside the F11 window in the Graph Parameters tab : distance from the middle point of the shell element or from its nodes. (In case the nodes option has been selected the average of all is displayed. These two options can be combined, and in this case again the average distance of all will be displayed).

Switching to the SGRAPH view mode ANSA is calculating the distances and such a procedure might take a while. To halt the process one can press the Break key.

Transparency ( enabled in ENT/ PID/ MID drawing modes)

When a Deck Module is active, in several functions as well as while working with the Database browser lists, the entities that are related with the activated function remain in normal drawing on screen while all the rest become transparent in order to facilitate selection and identification of the important entities. The “transparent drawing” can be temporarily disabled by Ctrl+Shift.



General Buttons: The bottom menu contains group of buttons which are available along with any activated Module. They can also be added in a User Menu.

FOCUS ISOLATE : the pull down menu is reorganized and new functions added.

FLANGES

• PROXIMITY : locates potential flanges based on the following recognition parameters

• LINK : locates group of parent and child Linked Faces

• SHAPE : detects candidate flange areas on each part

• CONNECTIONS : new option to locate flanges based on a search distance detection and the existence of connections on them.

RADIUS

HOLE ZONES: new function to locate element zones around holes

SKIN: this is the former OUTER/INNER function that isolates the outer or inner faces of a solid description or a complex assembly

TUBES: the function is now able to detect tubes taking into account Solid elements' Facets and FEM shell elements. A new option has been added to create a center line of the tube.

BAFFLES: new function to locate the “thin-wall” structures

SHORT PATH: indicates the shortest path between two elements (this function used to be the ELEMENTs> WRAP [Short Path] )

BOUNDS > SINGLE || TRIPLE || SPURS :isolates all neighboring elements to single and triple boundaries as well as those with irregular connection to their neighbors. (The function applies on FE-model elements only)

9776

BEST : After the selection of 3 points, the model is transformed so that the vector defined by the first two selected points turns parallel to the x-axis of the screen.

6498

OR – NOT : the functions affect FEM entities with no property also in PID selection mode



OR with PID selection mode : using box selection in empty space clears the screen

12780

OR – NOT – AND - !NOT in ENT selection mode : with double click (left or right) the selection is performed as if it was in PID mode.

D.UTIL The group hosts the Deck Utility functions :

D.INFO : deck report

CHECK : detect errors and verify model's integrity

VISIB BOUNDS : The Boundary drawing style is enabled for FE entities not related to Geometry also when in TOPO Module menu.

9921

W.SPOTS This group contains the following functions that used to be in the TOPO>WELD SPOTs group:

REALIZE: activates the Connections Manager

ERASE: removes connections via the Connections Selection Assistant

User is able to, simultaneously, measure multiple quantities between groups of different kinds of entities. For example, the user can consecutively select nodes, edges, shells or solids and watch the real-time alteration of the potential measuring results. The latter are displayed via a pull-down menu in the main Measure window and, therefore, the user has a full overview, in order to conclude to the final combined measurement result.

Note the ability to switch between different selection modes using the "1" key in the alphanumeric section of the keyboard and, additionally, the ability to switch between different potential results using the “2” and “3” keys, for “Up” and “Down” arrow-keys, accordingly.

Middle-mouse confirmation is demanded after the aforementioned procedure.

The results of the measurement are reported in the Ansa Info window and on screen.

The MEASURE function offers the opportunity for saving the applied measurements with the Store button on the initial Measure window. The latter are saved in a List and can be previewed, edited, deleted, or generally altered at a later stage. Note that all items in the List are Measurement Entities, which can be previewed in the Database Browser. The MEAS. toggle button of the VISIB group controls the stored measurements visibility as well.

The Clear button on the initial Measure window deletes real-time measurements. As real-time measurements are considered all measurements that take place while consecutively selecting entities, either before, or immediately after middle-mouse confirmation.

The measurement calculations are generally based on the Global coordinate system. An extra check box in the main Measure window offers the opportunity for calculation based on a Local coordinate system.

The results of the measurement are reported in the Ansa Info window, signifying the use of a Local coordinate system.

In order to return to the (default) Global coordinate system calculation, just de-activate the corresponding check box.

Measurement limits : The user can specify minimum and maximum limits of the measurement. The defined limits appear on screen, accompanying the measurement result and the whole edit-group becomes red, when exceeded.

LIST

INFO: prints the result of every selected measurement in Ansa Info window

REFORM: Opens the initial Measure window for direct access to the desired measurement modifications. With the specific option the user can radically change the whole measurement from the very beginning: change the measurement result type between potential measurements, alter the entities' measurement combination, set or remove limits and/or local coordinate system. Mind that using the Reform option the limits and local coordinate system can be massively changed.

Windows > Options > Measurements:

this section of the functions preferences handle the presentation of the measurements, such as :

color, printing format, number of digits, etc



TRANSF.

The Feature Area selection is available

New interface for the Geometric Transformations:

Once the entities to be transformed have been selected, specify the transformation type (Translate, Rotate, Scale, Symmetry, Transform) and input the necessary values.

The COPY or MOVE can be selected/redefined within the application window. The Move is auto-enabled after a Copy to better relocation if needed. A new Copy transformation can be applied after a series of Move transformations as well.

Use the [+] button (plus) to apply the specified transformation towards the given vector or

use the [-] button (minus) to apply towards the opposite vector. Use the [-] button to go steps back (undo). In some options instead of plus/minus there is the Apply button.

Use Middle-mouse-button , instead of the [+] or the Apply to proceed. Mind that repeating the same transformation is done with the Apply or the [+] button. A second middle-click exits the function!With the Finish button accept which ever transformations performed and exit, while with the Cancel button reject all transformations performed and exit.The Esc key works like the Cancel button while the Enter key works like the OK button.



Undo / Redo is provided: The respective arrow buttons host their History list which allows to scroll down the history of transformations and move back and forth between them



TASK Manager

Highlight Selected Entities related to Task items are now highlighted on screen once the respective button is enabled.

Output Specify the File name of the exported file or leave the suggested one. By having disabled the check box “Overwrite” and the file name specified already exists, you will be asked for overwriting but if the check box is enabled no warning appears.

9175

Contacts The Contact task items can be organized in Groups.

Checks/Fixes The checks “Part Thickness Penetrations” , “User Thickness Penetrations” and “Mesh Quality” can be defined up to two times.

Undefined Properties (DEFINED=NO) can be now detected within a Task.

10602

Geometry: Check for geometry errors is available within Task manager's “Common Model”.



Mesh Quality: Enhanced fix function. The fix function can also perform Reconstruction and Reshape on the Violating elements. The user can specify at the time of the fix the desired mesh parameters.

13325

Dummy Dummy – Depenetration: new function added in order to compress seat's foam due to dummy positioning. Moreover, the Initial Reference geometry keywords can be created based on each Deck.

12420

A position based on a Kinematic Configuration can be stored and Applied by the Save Position and Apply Position task items.

Seat Belt :

a) the Parameters option has been added in order to host all the settings to guide the seat belt creation when the task is executed. Moreover, user can select the PIDs for the seat belt elements (surface and line) that will be created.

b) seat belt task item can be defined without the existence of a dummy item.

Dummy on Seat:

-- Move Dummy to Seat: position the dummy onto the seat by arranging the proper translations/rotations.

-- Link Dummy and Seat: link the dummy and the seat by selecting the kinematic configuration for the seat.

Move Mechanism : dummy and seat moved at the same time. The Link Dummy and Seat has to be defined.

Move Limb to Target : the user selects the rigid bodies of dummy that has to be moved by matching points.

Connectors, GEB_xx

Connector and GEB items that reference connectivity with Properties of Barrier or Dummy items, keep the connectivity information if the Barrier or Dummy task item is removed. Thus, the Connectors and GEB_xx can be re-Applied when the Barrier-Dummy are reloaded.

ABAQUS The 'Initial Temperature' has been added (under FE Model group).



Data Management

Ansa DM toolbar button:

INCLUDE files

Data Management (ANSA DM) is able to handle Include Files (input deck files) as it does for ANSA Parts (ansa databases).

Include Files can have Version, Study Version, Representation thus they can be handled by the ANSA DM functions (Check DM Updates, Reload, Save Representation, Change Representation) through the Includes Manager.

File>Read model definition & ANSA.defaults

Add the variable :

part_id_convert = y

in ANSA.defaults under "Assembler Parameters" section to control whether to strip leading zeros from PART Module Ids and move trailing characters into PART Version when reading a product tree (e.g. VPM tree).

Compare DMs

Choose two different DMs and compare them in several categories (Parts, Boundary Conditions etc).

It is also available to copy or synchronize the contents between the two DMs.



Additionally, advanced filters can be used for the compared items. The User and Last Edit information is also listed.

Check DM Updates:

New options added:

- search for newer study version, based on the current version.

- search for common representation based on the newer version if one has been actually found. Common representations will only be reported, there will be no option to import them in the database.

8095 10939



Compare Versions

– Allow multiple selection: New option that allows switching between single and multiple selection of items in the results lists:

single selection, clicking on items is equivalent to choosing to keep the respective items.multiple selection only changes the status of selected items through the right mouse click options.

- Property thickness field is visible in compare lists even if there is no difference in the thickness value of the compared parts/files.

- New option to save the comparison Report as html or text(csv) file.

- Explode View/Reset can be applied from both lists.

- 'Show Differences Only' button has been removed from the Compare Versions window. Instead a 'Differences Only' option has been added in the Advanced Filtering tool.

In case of transformation matrices differences the user can select which matrix will be kept. Upon confirmation all selected changes are performed, 3 groups are created:

The first contains links of the new incoming parts/groups.The second contains links of parts/groups whose transformation matrix was affected.The third contains links of parts/groups whose version/st version/representation has been changed.

Save Representation : the whole procedure can be discarded, without saving in DM, by pressing Cancel on any of the pop up windows. Moreover, the new dialog boxes enable better communication.

An appropriate Report is given in the Ansa Info window (text) after Change representation, Sync representation or Save representation application.

Save Representation / Change Representation : multiple parts/groups can be selected. 7399



CAD Data Translators

CATIA translation: Important improvements / changes have been done regarding

• The recursively defined Catia V4 *.model files are now translated as single parts: the information of the respective parts and instances is taken. The part is named like the filename (without the path).

• The PIDs are created per BODY but if the BODY names are the same (for different bodies) the same PID is used. This is to avoid creating multiple different PID's for multi instanced .model files for each body instance.

• Significant improvements in “Color to PID” and “Layer to PID” options.

7340

NX translation : each part's attributes is given in the respective ANSA Part comments. The format is :

<Attribute title> : <Attribute value>

The attributes are written in lines (separated by '\n' in the comment)

Names of Curves and Points and the attributes of Curves and points are read in and given to the “Comment” fields of the respective entity card.

Moreover, the attributes of BODY are given in the “Comment” field of the respective Property card.



ANSA – TOSCA environment

A special ANSA environment dedicated to TOSCA Structure can be launched with the option

-gui TOSCA

this is an environment with limited functionality and requires a special license.



Connections & Assembly

Connection Manager

The REALIZE buttons that launches the Connection Manager is now placed in the W.SPOTs Group of buttons in the General buttons menu (bottom menu).

Connections List > Right click menu

Editing : the edit mode is now enabled for a single connection with double click in a field or with Edit option from the right click menu for massive modification of selected connections.

Show Only : keeps visible in the graphic area only the selected connections. Mind that any other already listed connections appear in green in the graphic area although they are are not visible.

Show Parts: makes visible the referenced components that are connected by the selected connections.

Show Parts Only: makes visible only the referenced components that are connected by the selected connections. Any other items are not shown.

Connectivity to Props || Connectivity to Parts : change the referenced connectivity information from Module-ID (Parts) to PID (Props) and vice versa while preserving the realized FE-Representations. It takes also into account the referenced includes and switch the IN-id to PID or Module-id respectively.

Auto detection of connectivity information:

- the settings of the window are now saved in the ANSA.xml for future use.

- “Clear Connectivity”: activate this check box in order to remove all connectivity information and update it with the detected by the function.

9163

Parts/Properties/Includes list

- left click on a component in the list does not affect the visibility of this component.- when a component is selected the connections are not selected in the Connections list.

- Right click menu

Remove from Connections : all selected items are removed from the connectivity information from all selected connections.Select Connections || Deselect Connections : select or deselect the listed connections that are related to the selected components.Show || Hide || Show Only : control the visibility of the selected component affecting also the referenced connections if only the “Apply to Connections” check box is enabled.Select All || Select None : select or deselect all listed components.

Read spots VIP2 : the connection's PID and material's data are interpreted as Comment. This is controlled by the variable vip2_info_to_comments = y which has been added to ANSA.defaults.

7067



Output VIP2 : exporting to vip2 file writes the Comment as PID, MID if these data are read from the connection's comment are valid. With invalid comment, vip2 file is produced with the old way and if "vip2_info_to_comments = y" a warning message is showed.

new output option "XML(pid)" : exports the connectivity of all connections to with the respective property id (PID) only.

This particular output option can be used for the xMCF format (an XML extension) that intended to be used by solvers as well.

Create Connections

TOPO>WELD SPOTs>CONVERT>

FE to Cnctn Pts : in the case of self welded Parts, i.e. connections between flanges of the same Module-id / PID) the same Module-id / PID is specified twice (or more if needed) in a separate column of the Connection Manager for every time the Part is connected to itself.

FE to Cnctn Pts : Rbody elements e.g. Nastran RBE2s with more than 20 nodes are not directly converted into connection points. A warning message appears while the view is zoomed to the elements that is highlighted in red.

FE to Seamline : PamCrash ELINKs to Seam-lines

FE to Adhesive : PamCrash LLINKs to Adhesive lines.

10992

7723

Connection Points can be aligned along a line, onto a surface or a plane by the ALIGN function (Deck>NODE)

10077

TOPO>WELD SPOTs>DEF.CNCT>MANUAL

Selection : the selected parts can be referenced either as single part in Pi fields or Multiple parts in Pi fields. In the latter case the user should separate each Pi field's components with middle click. Each selected group of components is highlighted in different color during the selection. The confirmation of selection is done with a second middle click. Box selection also works for this function.

Definition: apart of connection points (spotweld) user can now specify more connection types in more flexible way:

Select option : specify what to select in order to define the connection or a position. The “Point on face” allows picking freely onto Faces or FEM shells, while the “Point” option selects existing positions, i.e. nodes, hot-points, 3D-points, etc.

Connection Type: specify the type of connection. Options based on the main category as described below.

12472

13633



Single connection point

at the picked positions the Point Connection Type that is activated will be defined.

Multiple connection points

Point connections are defined but along a described line; either polyline (straight segments) or curve.

The connection points are created along the line based on the 'spacing' and 'margin' parameters.

Connection curve

a connection curve can be directly defined based on a line (polyline or curve) that is created according to the selected positions. Additionally to the other categories a Macro Area's Perimeter can be also selected.



TOPO>WELD SPOTs>DEF.CNCT> HOLES : new function that creates Bolt connections at detected holes either on Geometry or on FEM-mesh.

13471

CHECK CONNECTIONS : new function to check Total Thickness

the sum of the thickness of the connected part is compared to the given value. Connection fails the check if the total thickness of the parts is bigger than the threshold value.

11630

CONNECTIONS > Check intersecting parts

the "SHOW ONLY" button from the Checks list isolates also the relative flanges of the problematic connection. In case of FEM-mesh, 1 zone of neighbors is added.

10971

CONNECTIONS : Fix option besides the renaming of the selected connections, opens the connection manager with the specific connections already loaded.

Scripting CheckConnections( matrix InputConnectionsArray, matrix InputCheckDataArray, matrix OutputCheckReportArray );

12597



FE- Representations

Hemming FOLDING

The FOLDING FE-representation is used to fold a shell element flange on top of another, creating a hem. The hem, consists of an RBE3-HEXA-RBE3 element combination between the bottom and the top flange.

Note that the order with which connectivity strings Pi are specified is significant for the successful realization of the hemming. The last of the connectivity strings must be the component around which the hem flange will be folded and the first must be the component that will be folded as shown in the example below.

Variable folding angle in the same connection can be achieved if the connection is defined on more than 1 curves and the name of a curve includes "folding angle = XXXXX". If such a name is found , the XXXXX value will override the connection manager's value.

All 'folded' nodes (that belong to Macro Area perimeters) return to their original position after Erase-Fe.



Seam Lines

New representations related to durability and fatigue analysis: Heat affected zones can be created assigned a different Property. Zones width and projection's method are controlled in Connection Manager.

Y-JOINT-SHELL

OVERLAP-SHELL

CRIMP-WELD-SHELL

LASER-WELD-SHELL

EDGE-WELD-SHELL

To define the direction of the weld (in the seamweld types that support direction, i.e. Y-JOINT-SHELL, CRIMP-WELD-SHELL), the user can specify a vector by right-clicking on the connection entry in Connection Manager and selecting the option Set Weld Position. The weld position vector is defined by picking two points: The tail should lie on the Connection Line (left click on the seam-line and press middle click to confirm) and the tip should be a node of the model (left click on a node and hit the OK button). The weld position is read in by the xml connection file and is stored in the exported deck file as ANSA Comments.

If the user does not check the zone PID fields, then no heat zone props are created.

The ERASE FE removes any shells generated and the shells of the heat zones are assigned their original PID.

"Base sheet" for seamweld connections:

- "Base Sheet = P1 || P2 :specify the base sheet, without having to swap P1 and P2

- if you set "Base Sheet = Auto", then the parts P1 & P2 are scanned, and the thickest is assumed to be the base-sheet.

Mind that if you try to weld the seams the wrong way round, you will get NO F.E. Representation message.

Moreover, the "BaseSheet" is an attribute that is stored (and required) by the xMCF format.



The realization of the Y-JOINT-SHELL is illustrated in the following images. The heat zones in different properties and the way the weld shells can be created are shown.

All the above can be specified in the Connection Manager. Similarly (with less options in most of them) are realized the rest of these new seam weld types.

The seam weld settings, including the weld position, are read in by the xMCF file in xml format. Mind also that Connection Manager can output this new xml format : XML (pid).



Additionally 5 new representations for Seam Lines, dedicated to FEMFAT solver, are also available :

Y-JOINT-FEMFAT

OVERLAP-FEMFAT

LASER-WELD-FEMFAT

CRIMP-WELD-FEMFAT

EDGE-WELD-FEMFAT.

"Weld type" pull down selection specifies the materials that will be assigned to the heat zones, according to FEMFAT modeling guidelines.

coordinate systems are assigned to the welding nodes:

C100 : Welding seam.

C102: End of welding seam not welded around.

For the Y-JOINT-FEMFAT : no "weld shells" , only heat zones are created.

All the FEMFAT-seamwelds create heat zones that are surrounding the welding cut ( end of welding seam is welded around ).

SEAMLINES (Y-JOINT-SHELL, OVERLAP-SHELL, LASER-WELD-SHELL, CRIMP-WELD-SHELL, EDGE-WELD-SHELL )

Realization of HeatZones With the option 'Weld Around' enabled.



Spot Weld Lines

The spacing value S, for the distribution of the spot welds along the spot line, can either be a positive or negative real number.

A positive spacing value "s" with a margin value "m" implies that upon realization, priority will be given to the preservation of the margin value "m". Thus, the resulting spacing value may vary between "s" and "2s".

A negative spacing value "-s" with a margin value "m" implies that upon realization, priority will be given to the preservation of the spacing value "s". Thus, the resulting spacing value will be as specified, while the actual margin value may vary. In this case, during the output of connection information in xml or vip2 format, a positive spacing value will be exported.

Contact Realizations

DYNA SPOT WELD [Spot Weld Points/Lines]

RADIOSS WELD [Spot Weld Points/Lines]

HEXA CONTACT & COHESIVE CONTACT [Adhesive Lines/Faces]

CONTACT : [Seam Lines]

The field “Contact ID” has been added in the following FE-Representation settings where contact(s) is (are) defined automatically by the realization.

- Contacts that take 'single surface' are not accepted as an input to 'Contact Id' field.

- The new elements (e.g. hexas/beams/cohesives/springs) that are created are placed in the sets referenced by the specified contact, if “Contacts” and “Create Single Contact” check boxes are enabled (where both these check boxes exist; or where only the “Single Contact” check box exists).

- if "Create Single Contact" is disabled (or where there is no this check box), then the given contact is used as a TEMPLATE. Connection Manager will look for a contact that matches the template (i.e. named 'SPOTWELD CONTACT ...', whose master set contains the shell properties needed AND for which the values of fields in the edit-cards all match) and will update its sets. If no matching contact can be found, one will be created by copying the template.

- The 'given' contact must exist and it must support both master & slave sets.

- Merging of contacts does not take place when Contact Id is given.

Point-to-Point Connections:

In case of FE-Repr. elements that are connected to the mesh the projections, and therefore mesh reconstruction, is not performed if a node already exists at the projection position.

The properties, materials, rupture models and coordinate systems, that are automatically created by the connection manager, are erased when the Representation of the connection is changed or the connection is deleted, unless they are referenced elsewhere in the database.

10857

RBE3 pinflags : the representation that contains RBE3 will have as default the following settings:

'Use Separate REFC pinflags' = ON'REFC pinflags' = 123456 , 'RBE3 pinflags' = 123

ERASE FE : Hot-Points on the mesh nodes (Macro Area) where the connection elements were attached are now removed after the FE-Repr. deletion



SpotWeld Point/Line

PAM-PLINK

'Connect To Mesh' option is removed.

'Do Not Move' and 'Dist From Perimeter' options have been added.

The value used in the SPOTRA is compared to the available distance taking into account the new options status.

The 'Dist From Perimeter', works even if SPOTRA = 0mm.

The 'Dist From Perimeter', is useful for cases where it makes no sense to have the spotwelds too close (or outside) the bounds of a flange.

When an existing property is given in the IPART field the values specified in 'Search' , NGESP, SPOTRA and 'Create rupture model' are checked if they match with the existing Plink Property and the used Link Material. The PLINKs are realized but the existing PLINK Property is not changed. The input values are ignored and respective messages appear in the Ansa Info window.

9986

9086

SpotWeld Point/Line

TIE CONN3D for abaqus.

It creates a TIE contact between the nodes and shell properties of the connection's connectivity. CONN3D is always directed from P1 to P2.

There is an option not to create the CONN3D if there is no physical gap between the flanges.

14307

SpotWeld Point/Line

ABAQUS FASTENER : In order to directly reference the Connector Section within the Fastener's card, keep the 'Use connector' check box inactive and specify the CONNECTOR PID. This will create a Connector Section whose ID is referenced in the Fastener's card [CONN.SECTION].

10433

Seam Lines RBE2 , RBE2-CBEAM

"Force Node To Node" : When activated ( default = off ) it will attempt to force 1 to 1 node connections between connection parts. It works only when seamline "snaps" a feature line in both assembly parts ( in the other cases "node to node" was already achieved by projections ). Also , the feature line must be single and continuous on each part ( otherwise seamweld creation will continue as if option was off ). In that case , the 2 perimeters and nearby shells are reconstructed to achieve the desired result, as possible.

4915

Seam Lines CONTACT

Width [W] column is taken into account when adding the flange's nodes to the contact. Nodes within distance 'W' from the edge of the seamweld will be added to the contact.

Session Save Session (right click menu)

The option to save Only the Parts that failed (do not have OK status) has been added. This option allows further handling of mesh improvement.

A Single ansa file can be saved consisting of all parts of the session or each Part can be saved separately.

Import Meshing Files (right click menu)

Use this new option in order to update parts that had been “given” for further mesh improvement after the Batch Mesh.

Once a Batch Mesh session has been completed particular Parts that had failed the desired mesh quality could be saved in a separate ansa file. These files could belong in different sub-assemblies (hierarchy) and they could have multi-instantiated parts as well. When they have been improved and the ansa file is saved, there is a need to Update these parts inside the initial model in the proper position in the hierarchy structure. The “Import Meshing files” finds the respective parts in the initial file (i.e. same Module ID, same Name, same Representation) and automatically updates them with the “incoming” (mesh corrected) parts of the picked ansa file (that is selected via the File Manager). Moreover, it performs Synchronization of Multi-instantiated parts.

Presentation Parameters

Quality criteria (Shells & Solids)

- the user can customize the color for the criteria (for the element that violating the criterion in HIDDEN drawing mode)

- the visible criteria in the F11 window can be customized by the [Edit Visible Rows]

- different threshold values can be defined for shell and solids

New quality criteria

Shells:

• stretch• triangles per node• mesh distortion• distance from geometry• distance from origin• multi violation

Solids:

• stretch• collapse• distance from origin• multi violation



Ranges [Enabled by the respective check box]

The mesh quality by means of given criteria can be further evaluated using ranges between the Best and Worst values that can be calculated for the criteria. There are 4 default ranges (Best, Good, Failed, Worst) for quality evaluation while the user can Add/Remove ranges.

The user can specify the accepted percentage of the elements that fulfill each range's limit value along with a weight factor for each criterion and a penalty value for elements exceeding the thresholds in order to estimate the mesh quality. i.e.

In the example depicted above for the min length:

The “Worst” value is 3 with Percentage 100%, which means that ALL elements have to be “better” (larger in this case) than this threshold value. Next there is a user defined range “Custom” saying that 97.5% of the elements should be larger than the value 4. The “Failed” value (which is the basic threshold value) should be satisfied by the 95% of the elements, etc. In other words according to these settings only 5% of the elements are accepted if they exceed the “Failed” threshold value.

Along with the threshold values there are penalty values assigned for each column and a weight factor for each criterion. These are used to get a visual inspection of the mesh quality and locate the areas suffering by particular quality criterion.

The penalty value of an element is equal to the sum of each criterion value, multiplied by its weight factor and the penalty value, divided by the sum of the weight factors.

For elements that have a criteria value between the thresholds of the ranges the penalty pi will be calculated by the interpolation between the max and min values of the range.

A quality evaluation is calculated for each part according to the formula on the left:

The new color view mode QGRAPH (controlled by the F11>Graph parameters) displays (only in SHADOW mode) the above evaluation (penalty value) or any other selected criterion.

The cells in the criteria accept also a custom range by placing it in parentheses: "5.4 (90%)".

Otherwise, the common range will be considered ( "5.4" ).



QGRAPH color view mode / F11>Graph Parameters

Shell elements can be colored according to their quality, based on a certain criterion.

Once the ranges have been defined, select “criterion” as the option to plot for the “Quality Graph by: “

Choose the Color Bar Limits [Visible || Whole DB || User min-max || Ranges defined min-max]

Choose the Coloring rules in the Color Bar ColorsPalette (add/remove and edit colors if needed), Unique Color , unique color for each range

All filtering and modification capabilities are integrated as list features.

Quick filtering of the list entries can be achieved by typing filtering keywords or regular expressions in the field at the top. As soon as the user starts typing, ANSA suggests alternative filtering possibilities with auto-completion. The alternatives are listed in the drop-down menu and the user can navigate through them with the up/down arrow keys. Pressing ENTER applies the specified filter.

Typing an integer number automatically detected as id filtering while typing alphanumeric characters in the filter field, it is automatically considered as name filtering.

Quick Modify : The attributes of the listed entities that were added as columns in the list can be quickly modified without the need of editing their cards. Quick-modification for an attribute of selected items can be achieved by typing the modification expression in the field that appears with right-click on the column header.

Besides the simple and quick filtering and modification, advanced tools are provided for more complicated applications:



Advanced Filtering Procedures are performed by the Advanced Filter window which is invoked by the Advanced button in any List.

On the Filter Name section, all advanced filters already defined for the entities of this particular list are listed. The user can add a filter by picking the New option of the right-click menu. A defined filter can be renamed, copied or deleted with the respective options.

In the Filter Rules section, the actual filtering rules are defined: The attribute affected by a filter rule is defined in the left field. Typing the attributes name enables the auto-complete feature, which suggests in a pull-down menu all valid options. Additionally, this list contains any attributes that already exist as columns in the list.

Combinations of existing filters can be defined as well.

All the advanced filters that have been defined in an ANSA session or have been invoked through the ANSA.xml customization file can be found in the Filters window, under the Database toolbar button or through the Windows>Database menu option. The Filters window appears by default as a tab in the Database Browser window.

Advanced Modification Procedures can be applied through the Modify window which is invoked by the Modify option of the right-click menu in any List. The entities to be modified are the ones that are selected when the Modify window is invoked.

The attribute affected by a modify rule is defined in the left field. Start typing the attribute's name enables the auto-complete feature, which suggests in a pull-down menu all valid options. Additionally, this list contains any attributes that already exist as columns in the list or have been used for modification before.

The modification pattern is defined in the field on the right. A modification pattern can either be the literal new value the attribute should get, or a Modify Syntax expression. Expressions allow the modification of attributes based on their current values or based on the current values of other attributes within the same card.

! Note that when the Modify window is invoked for a list where a modification had taken place before, the last modification rules applied are displayed.



Additionally to the method through the Filter Rules and Modify Rules windows there is the option to choose the fields to be filtered or modified through the edit card of the listed entities accessed by the “Open Card” button.

The “edit” card is available only for the type but not for the group, i.e for Shell Properties or Beam Properties but Not for All Properties.

The card of the respective (selected) entities opens. Enable the label of the field and type the filtering or modification expression and thus perform the filtering/modification directly in this card, without creating filtering or modification rules by adding fields.



Load Curves

Data Table

Within the Database Browser List the fields of “curve” definitions can be treated (Filtering/Modify) , e.g. :

INCLUDEs The Includes Manager has been moved from the Deck>Auxiliaries Group and is now accessed by the MENUBAR>Windows>Database. Therefore can be active along with other functions.

When selected entities (from a List) are dragged and are about to be dropped into the Includes list, a New Include can be defined directly if the entities are dropped onto the [New Include] box.



SET The SETs Management window is now a tree form list

This form allows direct information of the Set's contents and also definition/update of the Set by “drag-and-drop” from the Database Browser list into the set.

When selected entities (from a List) are dragged and are about to be dropped into the SET list, a New Set can be defined directly if the entities are dropped onto the [New SET] box.

When more than 10000 entities are selected, the drag and drop operation can be performed by dragging the [drag selected] box that appears.

Create a new Set options:

i. Select entities in the Database Browser list and drop them in to the open SET list onto the [New SET] sign. A set is automatically created containing the dropped entities.

ii. Create a Set with the “New” option (right click menu or New button) and then drag and drop entities, selected from the Database Browser list, onto this new Set. Alternatively use the “Modify Contents” option to enable the respective mode that allows selection from screen.



The “Modify Contents” opens the 'Modyfing SET ...' selection mode window where the type of entity that should be selected is chosen. Along with this a List window opens with the entities of a particular type (the one chosen in the 'Modyfing SET ...' selection mode window).

The entities already contained in the set (if any) are marked in the List whereas the 'In SET' column displays in red the number of the contained items of each type.

Use Ctrl+left_click to deselect or select entities from the List or use left / right mouse button to select/deselect from the screen. Related selection tools appear to facilitate the selection from the screen.

middle click to confirm the set's contents modification.

Double click onto a Type label within a SET to open the Database Browser List with the entities of this type. If the Browser List is already open, the List switches to the proper type (the one picked in the SET).

The Add option [right click menu]

Using this option you can add Edges, Solid element Facets, Ranges or Exclude definition.



The Edges and Facets options enable screen selection. Mind that Edges and SolidFacets can be also added in a Set using drag-and-drop from the Database Browser list.

The Set Range option opens the RANGE card where can be specified the Type [NODE || ELEMENT || PROPERTY] and the START/END Ids.

The Excluded option allows the exclusion of entities which otherwise would be included in the SET. Once you have enabled (Add) an Excluded section within the set (appears as DELETED), you can drag and drop entities into this Excluded section.

Remove option [right click menu]

With right click onto a Set's type of entities (e.g. Property) all the items of this type can be removed from the Set.

Right Click on RANGE > “Convert to Entities“ :

converts the range to its entities. The contained items in a range (currently existing in the model) are placed in the same set (according to the Type they were defined in the Range) ; the Range definition is removed.

11548

A SET is now able to contain SETs, ANSA Parts and ANSA Groups.

PROPERTY LIST

The Property List is now open by the MENUBAR>Windows>Property (appears also as a toolbar button by default) and the Database Browser as well.

The PROPs> INFO, PROPs> APPLY are now integrated in the Property list as “Modify” and “Apply” options (available also in the right click menu).

Apply: firstly select the property, press Apply and then select the elements to change their property.

MATERIAL LIST

The Material List is now open by the MENUBAR>Windows>Property (appears also as a toolbar button by default) and the Database Browser as well.

The MATs> INFO, MATs> MATDB are now integrated in the Material list as “Modify” and “Material DB” options (available also in the right click menu).

Moreover new options added:



Change Type : switches the selected material to a compatible type that can be picked from the “Compatible material types” window that pops up. Mind that the Material card has changed and does not have the “Type” switch menu, thus the “Change Type” has to be used.

Map Materials : opens the “Materials Mapping List” in order to specify the mapping rules of material types between different pre-processing Decks. The material mapping takes place during File>Input and when the Mat-Sync is performed (by the Property List).

New:

when a Material Database is already loaded a pull down appears with options:

Form Library : opens the Material Definition list with the Supported materials to choose the proper type.

From Material Database : opens a list with the materials that are loaded in the Material Database to choose the proper type.

When the Material Database is empty (for this particular Deck) the New button opens the Material Definition list, as it does for the From Library option.

Material DB : drop menu that opens the Material Database window with the List option and hosts the Copy to DB, Update from DB , Compare to DB which are moved in the drop menu and do not exist as options in the Material List or the Material card.

Material Database

The Material Database is now invoked by the Material DB >List within the Materials List.

The Auxiliaries button drops a menu with options (based on current Deck) to open the Curve DB, Table DB, Rupture Models DB etc., i.e. the entities that are referenced by the Materials loaded in the Mat DB.

Updating Materials from the Material Database

When a material from the MatDB updates an existing material in the model or just copied to the model, the referenced entities, i.e. Curves, Tables, etc. are compared to already existing ones in the model (taking into account ID and Name) and in case identical entities found, they are used in the material's card instead of creating new



entities. No duplicate entities (e.g. Load Curves) are created by copying the same material from Mat DB to the Model.

Moreover, ID and Name of the incoming material (the one in the Material Database) have higher priority and replace any existing ids and overwrite names. The achieved result is having the same material with the respective one in the Mat DB.

Comparing materials

During the comparison between materials in the model (Material List) and materials in the Material Database the activated check boxes [ compare by Ids, compare by names, most similar ] are taken into account also for the auxiliary entities referenced by the Materials, i.e Curves, Tables, etc. and any differences between these auxiliary entities are reported, e.g. Curves with different ID.

KINEMATICS

A multi body dynamics solver integrated within ANSA has been introduced in order to allow the user to efficiently position complex kinematic mechanisms such as convertible roof, hood, occupant seat, dummy models, suspensions and many more that might need an accurate positioning.

A rigid body dynamics solver requires rigid bodies and joints in order to provide a solution. For this purpose special ANSA entities have been introduced in order to create kinematic rigid bodies out of FE models and kinematic joints out of FE joints. These kinematic entities are used by ANSA for the internal solver and they are not related to the corresponding FE solver entities.

KIN_RBODY ANSA kinematic rigid body. It consists of a combination of elements, properties or nodes.

KIN_JOINT ANSA kinematic joint element. It is used to connect two rigid bodies and allows relative motion between them according to its type (revolute, spherical etc.)

KIN_CONFIG ANSA kinematic configuration. It is used to set-up a specific rigid body motion by allowing certain joints to move.

KIN_POSITION Saved positions of a KIN_CONFIG

AUXILIARIES > K JOINT & AUXILIARIES > K RBODY

K JOINT and K RODY are functions that allow the editing of the results given by AutoMech and Mech From Sets (both placed in the SAFETY group of buttons)and the creation of Kinematic Rigid Bodies and Kinematic Joints.

AUXILIARIES > K CONFIG

This function allows the creation of kinematic configurations. With the locking and unlocking of kinematic joints configurations such as backrest tilting, seat sliding, seat height adjustment etc. can be created.



Kinematic Rigid Body

For every rigid body, all of their entities are listed. Entities can be added in a rigid body by “Drag and Drop” operations from the Database Browser.

Kinematic Joint

RIGID BODY 1,2: the two rigid bodies that are connected by the joint. If any of the joints is 0, ground is assumed.

ANCHOR: Location of the joint.

AXIS: Orientation axis of the joint

Joint limitations: Joint limitations and current position of the joint.

An additional use of KIN_JOINT is the creation of a boundary condition. A very common boundary condition is the “Ground”, where, for instance, the seat is “Fixed” in space.



Kinematic Configuration

Kinematic Joint: the available mechanism are listed. In a tree view the available joints of each mechanism are also shown.

Kinematic Configurations: With “Drag and Drop” create the different types of Kinematic Configurations.

A joint needs to be set up as an actuator that is going to drive the mechanism. This is done by the Set as Actuator option.

The Move Joint option allows for the movement of mechanism. The user drives the actuator joint and in turn a kinematic rigid motion of the mechanism is performed

Each position of the model can be stored by the Save Position. At the moment a new position is saved, it is stored in a form of a KIN_POSITION entry. These positions can be easily retrieved and used by the Move To option, where all the previously saved positions are listed.

The kinematics tool allows the user to output transformation information of the mechanism in order to avoid re-writing a model output. This is done with the Conv to _ NMAP in Abaqus, NODE_TRANSFORM in Ls-Dyna, TRSFM in Pam-Crash) option in the right mouse pull down menu. The options are to select either a saved KIN_POSITION or the current position by selecting Reference Position.



SAFETY A new Group of buttons labeled SAFETY has been created for ABAQUS, LS-DYNA, PAM-CRASH and RADIOSS Modules.

It hosts the Dummy/Safety options used to be in Auxiliaries Group.

When importing a dummy model (ABAQUS, LS-DYNA, PAM-CRASH) the hierarchy structure that exists is interpreted to the respective Kinematic Configuration.

AutoMech In cases where a dummy model may be missing its hierarchy-tree definition this function creates the appropriate dummy hierarchical structure, that is a kinematic rigid body configuration.

This function replaces the previous Auto-Create.

Mech from Sets This function creates a mechanism configuration in a stepwise fashion. Since the parts of a model that consist the rigid bodies of the kinematic mechanism are usually predefined node sets, these sets (for the rigid bodies or the connectors) are used to create the kinematic mechanism.

The user just selects the node sets from a list, and then is guided through the creation process: to accept or not every kinematic rigid body. The user may also give a set of joints and ANSA will create the K_JOINT and the K_RBODY.



! Note that only one side of joints is needed due to symmetry. Thus for simplicity and to avoid mechanism locking, the joints of the one side need to be accepted and the other to be rejected.

Pedestrian Use this function to set up a pedestrian test based on the EuroNcap protocol (also for other protocols and regulations as well after manipulation). The function has the following capabilities:

- Creation of the “Wrap Around” lines for the bumper and the bonnet.

- Creation of Raster of Target Points on the Bonnet.

- Detection of critical Target Points based on hard surfaces.

- Headform and Legform positioning.



EuroNCAP lines

Front Car: This field requires the set id of the front of the vehicle.

Ground Point Z: In this field the Z direction of the xy plane that defines the ground is needed.

Apply on: Gives the option to apply the lines on the Bonnet, Bumper or both.

Stepsize: The stepsize value determines the resolution of the curve relative to the underlined Front Car set.

Target Points:

Creation of target points and critical point detection The critical target points are detected by providing the SET that contains the hard parts (such as the engine block, the battery etc.). ANSA will detect the points based on the minimum distance between the raster points and the hard parts SET at the given impact angle.



Raster Length: Is the length of every square of the raster.

Raster Side Tol: The raster is generated from the middle of the bonnet and outwards. This tolerance dictates the length of the last step of the raster closing on the reference lines. If the length of the last step is less than the side tol, this length will be added to the last step of the raster. If the length of the last step is greater than the side tol then a raster step of that length will be created.

Windscreen: The windscreen set is used to better detect the points on the A-pillars. If a windscreen set is given target points will be created on the side reference lines.

Hard Parts: A SET of the hard parts of the under hood.

Search Step: Step in x and y directions per EuroNCAP lines area.

Points: Specifies up to how many points should be detected per EuroNCAP lines area.

Test Zone: Specifies the test zone per EuroNCAP protocol Adult or Child

Impact Angle: The impact angle of the Headform

The raster is created based on the Test Zone selection. The raster is made of null beam elements and any point can be chosen to position the impacting device.

The critical points detection function creates 3D points and a measure entity that show the critical distance. 3D points can be picked as



position for the impacting device also.

Additionally all the points of the raster and the critical points can be exported as a text file by pressing on the Write File button.

Headform – Legform positioning

parameters for positioning the impacting device are defined

Besides the Headform positioning, now the tool is able to position Legform model that has to be defined as a SET. Its ID has to be input in the “Legform” field.

Trans Dummy The Translate function performs a translation of the whole Dummy model by moving it based on the global coordinate system. In order to have this function working properly, the dummy model has to be properly defined in advance.



Rot Dummy Rotate Dummy option is used to rotate the whole dummy around its H-Point. The Interactive Movement Sensitivity slider regulates the sensitivity of the mouse movement relative to the model movement during interactive mouse rotations. Far Right is maximum sensitivity where far left is the minimum sensitivity.

Rotate Dummy Part option is used to rotate dummy parts (limbs). The rotations can be performed through the window or interactively from the screen (hold down the left mouse button while moving the dummy part).



Move Limb :

A new useful function for performing minor translations of limbs such as moving the upper limbs onto the steering wheels, or moving the lower limbs onto the pedals.

With successive left mouse button pressings the user selects the length of the limb (sequence of rigid bodies) that will participate in the motion. After the selection of the limb two points are needed for the translation, one point on the limb and one target point.

Interior : hosts the functions :

Interior [ FMVSS 201 / ECE R-21 ] : positioning of the headform pendulum for the simulation of the occupant protection in interior impact laboratory test according to the FMVSS 201 standard.

Interior [ FMVSS 201U ] : positioning of the headform pendulum for the simulation of the occupant protection in interior impact laboratory test according to the FMVSS 201 standard.

Seat Depenetrate :

A new option to create the initial geometry has been added:

in LS-DYNA : *INITIAL_FOAM_REFERENCE_GEOMETRY

in ABAQUS : INITIAL CONDITIONS, TYPE = REF COORDINATE

in PAM-CRASH : METRIC



SeatBelt :

The option to specify the PID for the seatbelt elements (shells, bars, etc.)

Model Cut Cut Model

Handling of Unconnected parts :

Delete None : No unconnected part is deleted

Delete All : All unconnected parts are deleted

Delete All/Exclude cutting box interior : Delete all unconnected parts, except those that lie inside cutting box(es). Use this option in combination with one or more cutting boxes to selectively delete unconnected parts.



Model Cut Check Cut

Applied on selected 'cut planes' and reports any elements that belong to both 'substructure' and 'user area'. Also provides functionality for moving selected planes by a specified step ('+' and '-' buttons) and for expanding or shrinking moved planes so that a closed box is formed. 'Expand/Shrink' only works for planes that are mutually orthogonal.

Edit cards the switch option “by” (node || set) has been added in several entities edit cards, that allows changing the definition method of the entity. This option enables the creation of several entities by script.

for instance:

NASTRAN : SPC , SPCD , CONM2 , NOLIN, ...

ABAQUS : BOUNDARY, TYPE=DISPLACEMENT () , MASS, CLOAD

ANSYS : D , F, …

LS-DYNA : MASS, BOUNDARY_CONSTRAINED_MOTION_[NODE/RIGID/RIGID_LOCAL], LOAD_NODE_POINT/*LOAD_NODE_SET/*LOAD_RIGID_BODY, ...

SET > Orientation of Set's Entities

All “orientable” elements (e.g. Shell, Gasket, Continuum Shell, etc) and the respective Properties contained in SETs, can be given a particular Orientation (SPOS / SNEG). This is a characteristic of the Set and can be assigned per contained entity, i.e a Shell property defined as Oriented= SPOS in one Set can be Oriented=SNEG in a different Set. Also two Properties in a Set can have different Orientation.

The orientation of the exported surface, based on the Set (Output as surface), is specified either by the “ORIENTATION” type or by the Entity's Orientation that is now available.

In order to define the orientation on a set's contained entity:

- Open the SET management window and click on Set's contents that need to specify Orientation.

- The Database Browser List with these entities (e.g. Properties) appear with the Column “Oriented”. This appears as an option within the Entity's card as well. However, the field/column becomes available only through the Set management.

Create a new definition through the SUBSTRUCTURE ANALYSIS CREATOR window. Cutting Planes (already defined by MODEL CUT function or via the New button) should be Added so to define the “User Area volume”.

Visualize the entities of the substructure with the Preview button.

The substructure is created the moment the output is made. ANSA writes the model and following 'cuts' it and writes also the substructure file.

During output all necessary in CONTROLs cards (i.e. SUBRUN) are updated in the substructure file and the SUBDF_/_ definition is automatically created (and written) in the main file.

13433



RADIOSS

RADIOSS CONTROLS new window. 11868

CLOAD and GRAV are supported according to Radioss v5.1

ANSYS

Input Support input of *.cdb files exported by ANSYS 11.0 Workbench. 12651



CFD Decks

ANSA provides now DECK module menus for the setup of cases for CFD++, FLUENT (2D and 3D), OpenFOAM, StarCD and UH-3D.

Select in advance the required solver DECK as this will allow the proper display of Property cards for the specification of Boundary Conditions.

It is recommended that ANSA is started with the option -gui cfd

This will allow the better setup of the software interface for CFD pre-processing.

Size Box

The user can control the size of the surface and the volume mesh in selected areas of the model using ANSA Size Boxes.

Size Boxes are flexible entities and can have any orientation or form, thus making mesh size control very precise.

They influence the functions:

- PERIMETERs>A.SPACING [CFD]

- MESH GEN.>CFD

- VOLUMEs>MESHV [Tetra CFD] and [Hexa Interior]

Size Boxes can be created in the SIZE BOX Group of buttons in every CFD Deck.



CFD++ For CFD++ the user can specify in the Shell Property card whether it is of type Boundary for 3D Simulations or Cell for 2D simulations.

OpenFOAM ANSA supports input and output of OpenFOAM v1.4.1 and v1.5 file structures.

The user can specify the solver settings, boundary and initial conditions for a full simulation.

STAR In the STAR deck the user can specify boundary conditions for Star-CD and Star-CCM

e.g. specify the TYPE to e.g. Wall type in Shell Property card

The volume properties can also be specified as fluid or solid.

UH-3D For UH-3D Deck the user can specify in the Shell Property card the boundary condition type and magnitude for:

Surface Temperature

Surface Heat Flux

Mass Flux

Grill Resistance

During output the user can renumber the model.

FLUENT 3D The assigned PIDs of shell (Fluent Faces) and volume (Fluent Cells) elements will be translated into Fluent 3D Zones during the output, maintaining the same ID and name. If there are any spaces in the PID names these will be converted automatically into underscores “_” during output, for Fluent compatibility.

If ANSA detects Properties with identical names, it will rename them (adding a “:1”) during output to avoid conflicts in Fluent.

The type of boundary condition can also be prescribed in the EDIT card or shell and volume Properties.

ANSA supports the input and output of both *.msh and *.cas ascii and binary files.

FLUENT 2D For Fluent 2D meshes the geometry and mesh should be constructed in the z=0 plane.

The PIDs of ANSA shells will be output as fluid 2D cell Zones in Fluent.

Boundary Condition (BCs) names and types along edges (2D Face zones in Fluent) must be specified on ANSA SETs.

If no SETs are created then by default all free boundaries are written in a default-exterior Zone of Wall type, and all interior Faces in a default-interior Zone. If needed they can also be separated later in the solver.



PERMAS

A new Deck module has been added for set-up simulation models for the PERMAS solver.

Directly Input and Output of permas deck files is supported.

Substructure analysis (Multiple Components) can be handled in ANSA via the Includes Manager. Mind that identical Ids are not allowed for similar entities in different components.

Preserve the user specified names of Sets (nodes and elements) 13984

MEDINA

I/O Support read/write in bif-file of the LS-Dyna keyword *DATABASE_CROSS_SECTION.

13474

Input Import of TRIAV and QUADV elements as MEMBRANES for MEDINA - PAMCRASH.



MORPH

Module's Buttons group modifications.

Synonymous buttons (like SLIDE, OFFSET etc), previously located in different menus, have been unified under the new MODIFICATION group. This group has replaced the former BOX MORPHING menu.

CHECKS: A new group of buttons that hosts the flag buttons (MORPHING, Hi.Li, TRANS, FREEZE , TANG), which are also available during modifications, in the respective window.

There are two modes:

Non-morphing mode: Boxes are simply reshaped in order to better fit to the model's geometry.Morphing mode: Boxes are reshaped and their loaded entities are morphed accordingly.

The MORPHING flag button (CHECKS group), enables the user to toggle between the two aforementioned modes.

A new visibility flag button (MORPHVIEW) has been added in the CHECKS group. Using this button the user can toggle between TOPO and MESH view, while being in MORPH menu.

Morph Settings

Special settings that are used during the Morphing process can be defined through the Windows> Options>Settings>[MORPH] function

''2D morph thickness'' : Defines the virtual thickness of the 2D-Morph Boxes.''Apply extra-fine tolerance'' : Applies extra-fine tolerance to the morphing functions, irrespectively to the current value of tolerance that is used through the OPTIONS>Tolerances function.''Box in Box morphing'' : Activates the Box in Box morphing functionality (see section 22.5.3).''Include morph points in load'' : Enables User to automatically load Morph Control Points, using the LOAD>VISIBLE function.''Ask for morph movement confirmation'' : Activates a Confirmation window after each Morphing action.''Color for linked'' : Activates the Color Editor for the Linked Boxes.



Geometry Morphing

Geometrical entities can now be loaded in Morphing Boxes and morphed accordingly.

The notification : ''GEOMETRY MORPHING INACTIVE'' appears in red color, at the right bottom of the graphic area. Activate the CHECKS>GEO_CHECK function in order to prepare the model (containing FACEs) for Morphing.

During the GEO_CHECK ANSA examines all the loaded Geometrical Faces and performs cuts in areas where they intersect Morphing Boxes. Thus, new faces are produced. These Faces are properly distributed to the appropriate Morphing Boxes. The Geometry Morph window appears listing the loaded Faces and reports any Conflict status due to “cutting” problems. These Faces should be placed into the proper Box by choosing the related Status option [IN || OUT]

All connection entities, 3D curves can be also morphed.



BOXES CYLIND>CONV2BOX

Using this function, it is possible to create hexahedral Boxes in place of cylindrical ones.

Case1. Select a Cylindrical Box without any concentric splits. One hexaedral Box like the one shown below is going to be created:

Case2. Select a Cylindrical Box with concentric splits. ANSA creates five hexahedral Boxes. One Central Box and four more located all around it.

Simultaneously, Morphing Parameters are automatically created in order to control the Length and Radius dimensions of the initial Cylindrical Boxes.

11307

2DMORPH>CONV2BOX: this new function creates 2 Hexahedral Morphing Boxes based on the selected 2D morph entity.

MULTIBOX

The user can create multiple Morphing Boxes in a single step.There are two main options. The Hexa-Block and the O-ring. Using the first, 27 boxes are created in a block-type shape while in the second option, six hexahedral boxes are created around the central box.

An existing Box can be selected as well

8091



OFFSET BOX

A new function to create Morphing Boxes.In this function the user selects an outer (single) Morphing Hatch and defines an offset value. The new Box is connected to the old one by the selected Hatch.

11305

CONTROLS HISTORY

The History during Morphing modifications can be recorded. Morph History States can be recorded through the Confirmation window, after each modification [Rec.Hist]. Additionally, History States can be recorded at any time using the HISTORY function. Using Morph History States, the user can jump at any time to any, previously defined State. Thus, it is quite easy to delete the mistaken Morphing actions.

Using the options under the Create drop menu the user can create a Deformation or a Curved Deformation Morphing Parameters, etc between the selected History States.

User Defined Tangency [EDGES>TANGENCY>USER]

The user is now able to define or modify the orientation of tangency on Morphing Edges, by specifying the desired vector or plane. There is also the option to set an already user-defined tangency orientation, as a Morphing parameter.

11310



CONTROLS NESTED>RB2TONESTED

Nested elements can be created from RBE2s.

The original RBE2 still exist after the creation of the nested element.

PARAM

New Morphing Parameters have been added:

SPIN :

The already known, SPIN modification function can now be performed through a Morphing Parameter.

CURVED_DEFORM :

Using such a parameter the user can perform Morphing, moving along a curve, defined by selected Morph History States. The user defines a factor between 0 and 1 morphs the model parametrically along the defined curve.

USER_TANGENT :

Morphing actions performed by modifying a User Defined Tangency, can also be saved and performed through the relative parameter.

MODIFICATION MOVE

New options and interface for Control Points movement. Transform and Scale options have been added.

11902

11903



DIRECT

The DIRECT function is now available also in the MODIFICATION menu. It is performed on Control Points in order to move them directly.

Select Control Points to be moved. Then define the Control Points that are going to retain position. Finally select the Control Points to move following strictly cursors movements. Press left mouse button in order to lock on the desired position.

FIT>EDGES

A new, friendly and convenient interface helps the user to modify edges and curves selections or to save them, as an EdgeFit Morph Parameter.

As soon as the function is activated the EDGE FIT window appears which is auto updated by the selections.

In case you need to modify a group of curves or edges, select it and press the ''modify'' button. Add more entities using the left button or deselect the already selected using the right one.

Press the ''Save as parameter'' button, to create an EdgeFit parameter based on the defined groups.

Press the ''Apply'' button in order to proceed with Morphing.

The Master/Slave Fit function of older versions, has also been incorporated here. There is also the possibility to add a slave Edge group by right clicking on the relative Master.

ALIGN : control points can be aligned on a plane along a user specified direction.

11909



DIRECT MORPHING

4S.FIT: A selection list appears and automatically updated by the selections made and allows the user to highlight and modify the groups of the selection.

The ABAQUS REFERENCE COORDINATES , the PAM-CRASH METRIC_NODES and LS-DYNA INITIAL FOAM REFERENCE GEOMETRY can be loaded and morphed.

12176



Optimization

Optimization Task

New capabilities in the Simulate Window

Through the simulation window, it is now possible to view an animation of the various steps defined by the design variables.

All the defined design variables are displayed in the upper section. Specify the number of the simulate steps to view in the animation session. Press ''calculate'' button in order the internal states to be calculated. After that, all the animation buttons are enabled and the user can proceed with the animation.

Except viewing the animation, it is also possible to save it in avi format using the ''Rec'' button.



TOSCA Structure

A complete interface for the TOSCA Structure 6.2 has been integrated into the Task Manager. The interface supports the TOPO, SHAPE and BEAD optimization for both CONTROLLER and SENSITIVITY algorithms. The graphics interface and the SETs functionality of ANSA can be used for the definition of the TOSCA groups and constraints.

Through the TOSCA Structure Task user can:

- Set up the pre-processing of the optimization problem. The Task Manager guides the user through the valid options according to the selected optimization case.

- Run all the tests that TOSCA provides (TEST1, TEST2,...) before start the optimization run and provides full report of the process.

- Invoke TOSCA in batch mode to run the optimization problem.

- Invoke TOSCA Smooth in batch mode to define the smoothed surface around the model of the optimum iteration.

- Quality improvement. After the definition of the smooth surface, the TOSCA Structure Task is able to improve automatically the quality of the surface using the RECONSTRUCT functionality.

- Definition of the validation model. Solid mesh is applied to the smoothed surface.

Additionally all loads and boundary conditions are re-applied to the solid in order to create a ready to run model and validating the optimum solution.

Mind that a special ANSA environment dedicated to TOSCA Structure can be launched with the option:

-gui TOSCA

this is an environment with limited functionality and requires a special license.



NASTRAN SOL-200

SOL200 has now been incorporated in the NASTRAN Loadcase under the integrated Design Optimization task item.



SCRIPTING

ANSA_TRANSL

Language &

main features

The ANSA_TRANSL file is now read from the '/home/user/.BETA/ANSA/version_13.0.1/' directory, instead the user home directory (i.e. : /home/user/).

Furthermore, there are some changes in its functionality.

Global code:

the global code is written inside the function CAD_Translate. E.g.

def CAD_Translate()

{

your code

}

Rest code: All the other commands are still written inside the function

def autoexec(), except the buttons creation.

To create user buttons use the command defbutton which creates the button and defines the function simultaneously. The name of the function is the same with the name shown on the button.

Moreover, you can define in which group the button will be created into, by writing the name of the group beside the defbutton command.

Example of creating buttons:

Old ANSA_TRANSL:

def autoexec()

{

AddUserButton("Do Something","DoSomething",1);

}

def DoSomething()

{

your code

}

New ANSA_TRANSL:

defbutton DoSomething()GROUP_NAME

{

your code

}

Thus, with the new way of creating buttons, every time you change the default script the buttons are updated automatically, and only active buttons remain visible.

!!! All ANSA_TRANSL files written in the old manner can be read by ANSA_v13.x, provided that they are in binary format.



The keyword 'const' has been added in scripting language

External files The use of external files in ANSA_v13.x has become more similar to the one in C language.

'#include' statement. The '#include' statement incorporates the contents of a specified file at the same point where the statement appears. Common static functions that exist in different include files can not be treated independently, and therefore only the last one is kept.

'#projectfile' statement. The '#projectfile' statement is another way to use external files within a source file. Its major advantage is that every specified file is treated independently, and thus, any common static functions are allowed.

!!! The '#projectfile' statement in ANSA_v13.x works similarly to the '#include' statement in ANSA_v12.1.x.

File>Script The File > Script button menu has the options to enable script editor and perform other operations related to scripting

Script Editor

Project Window. In this window you can create, control and execute a project. A project is a file that has references to many scripts, incorporated as external files.

View>Editor colors. In the new script editor you can select the colors you will use for each type of text, as well as for the background.

Windows. All the windows of the script editor are handled in the same manner as all ANSA_v13.x windows. Thus they can be visible or not, docked or undocked etc. You can control the script editor windows from the Windows drop down menu.



The File>Script>Default option opens a window where all loaded and added scripts are displayed. The index in front of each path indicates which is the default sequence. Always, the script with zero index is the default.

File>Script>Reload reloads ALL loaded scripts

Command line Command line execution. Execute a script function when starting ANSA with the -exec using brackets in the function's call

-exec function_name()

type any arguments for the function within these brackets.

Script Functions

Function CollectAffectedConnectionEntities has been enhanced.

An additional value 'AllEntities' is supported by the CONNECTION TYPE argument, so that all connecting entities can be collected at once.

An additional value 'AllAffected' is supported by the SEARCH OPTION argument, so that both internal and external connections entities can be collected at once.

New function 'FillGapFreeShells' for 'MESH>FILL>Gap (free)>Shells'. 12321

New function ReferenceEntities. 10606

Extra category "__CONNECTIONS__" added in "TypesInCategory" script function.

11578

New parameter added in script functions: TranslatePart, RotatePart, ScalePart, TransformPart, SymmetryPart, MirrorPartPoint, MirrorPartAxis, MirrorPartPlane.

You can specify the module id offset in the case of Copy-transformations, when creating a new part.

9888

New function FacesConvert converts link faces to normal faces 11742

New function OutputOpenFoamPoints, that outputs only points of the mesh.



New function CopyMatToMdb(). 12145

New functions KinematicsSavePosition and KinematicsMoveToPosition

new session functions added:

SESSION>MESH>SHELL MESH> PARAMETERS>DISTANCE_FROM_SURFACE

SESSION>MESH>SHELL MESH> PARAMETERS>DISTANCE_FROM_SURFACE_PARAM

SESSION>MESH>SHELL MESH> PARAMETERS>DISTANCE_FROM_PERIMETER

SESSION>MESH>SHELL MESH> PARAMETERS>DISTANCE_FROM_PERIMETER_PARAM

to set the respective fix quality parameters through script.

New function RunAllMeshingScenarios, that runs all active scenarios.

New Function RefineElements

New function MorphParamCreate to create parameters from script. 12652

GENERAL

ANSA terminated when trying to open a previously saved file with "save visible as" option containing an adhesive face. (Error appeared in v12.1.5)

11214

Tolerances window issue fixed. From now on, the pull-down option (draft, middle, fine, extra_fine) is saved in the ANSA defaults file.

9823

Corrected error of Saving mesh parameters. 10903

Corrected AREA and VOLUME calculation. 10291

Comma “,” can not be used instead of dot “.” for decimal point in card fields. Warning message is prompt so to avoid improper input.

9746

Geometry TRANSF.[MOVE] was not able to move Nodes on Macro Areas PERIMETER

13256

MEASURE: Wrong calculation of dx,dy,dz when measuring EDGE-NODE, EDGE-EDGE

13519

FOCUS LOCK: Fix improper selection of Lock view from a “long” pull down menu.

13903

File>Compress All : removed entities that were referenced only in sets, thus these sets remained empty.

14201

File>Open IGES reading problem related to mispositioned parts. 14653

STEP : Problematic CONS error fixed 7927

9912

File> Output CAD

Problem with VDA output : centers of circle curves were confused with the 3d-points and results in a wrong vda output. Now the Circle CENTERs are exported as “PC” instead of “PN”.

8419

STEP : Fixed problems in particular cases 1492



TASK Manager

Abnormal exit caused by selecting “Change” option on a particular script that merged ansa files into Task manager

9959

Fix Method option for Checks>Mesh Quality 13325


PAM PLINK : duplicate and unused mat_302 was created 10019

PAM PLINK : when IDPART field points to an existing property and the “Create Rupture” is enabled; the related material is not changed (i.e. no rupture model is created since this would change the given Property).

10020

TOPO>WELD SPOTs>CONVERT> FE to Adhesive

When Converting RBE3-RBE2-HEXA-RBE2-RBE3 to Adhesive lines the created adhesive lines get now the right connectivity.

11912

Fixed abnormal exit when applying node connections 7746

Thickness-to-Diameter mapping for Spotwelds was not correct for Connections which need projection.

10923

Connections (Lines or Faces) that had their 3D-Curves or Faces deleted are now not shown in CM, nor can they be selected.

4403

Wrong realized representations:

Seamlines > RBE3-HEXA-RBE3

Adhesive lines> RBE3-HEXA-RBE3 & HEXA-Contacts , with options 'Force Ortho Solids' and 'Preserve Width' active.

the rbe3 (or Hexa nodes in contact) are attaching upside down

13891

RBE3-HEXA-RBE3 : Zero Height HEXA

When the connection is between 3 parts or more, and one of HEXAs is of zero height, ANSA still creates the RBE3-HEXA-RBE3. It does not FAIL the connection as it should according to the FAIL ASPECT > option.

7864

Adhesive Lines: Bad Hexa quality in circular adhesive lines. Now a circular curve will produce all its hexas completely symmetrical.

14065

Read Reading an adhesive line from vip2 with H=0 is interpreted in ANSA as H=1.0 13776



BATCH Mesh Manager

Didn't accept holes with diameter smaller than ANSA node matching distance tolerance at reconstruct hole treatment

13772

Left unjoined perimeters on windows xp prof 64. Different results on different machines although the same file and parameters were used.

10313

Abnormal exit on particular case. 10761

More nodes were created along Holes' perimeters. The number of nodes on the holes which were near perimeter was not the same with the node number specified by the Holes treatment tab.

11213

TOPO

FACEs>OFFSET>[FACES] gave bad results 8495

FACEs> SHRINK : fixed error that caused unaccepted result in particular cases. 13456

CROSS SECTs>NEW>MULTICUT: unexpected termination when cutting elements (solids) giving small step length.

13638

CROSS SECTs>NEW>CUT did not perform a proper cut on faces 12211

CROSS SECTs>NEW>MULTICUT: did not calculate sections although this could be achieved by the Cross Section tool.

12259



MESH

PERIMETERs>SLIDE : Error caused distorted hole and abnormal exit.. 12331

13862

PERIMETERs>SLIDE | Batch-Mesh

if the SLIDE function performed onto holes after Batch Mesh the Faces were distorted and re-run of Batch Mesh caused abnormal exit.

3190

GRIDs > ALIGN : abnormal exit on Windows 32bit (in v13.0.0) 13808

14007

GRIDs>MV HOLE> [Slide] : generation of unaccepted elements 7261

SHELL MESH>MAP : in 2nd order MAP mesh the Middle nodes did not always follow the curvature of the face.

11841

(1114)

SHELL MESH>UTIL>[Open Hole] : if a big number was given for the nodes on the hole's perimeter the shape of the hole got deformed.

13706

SHELL MESH> RECONS | WELD SPOTs>MARK

After marking a Hot-Point the mesh Reconstruction caused collapsed shape.

12160

SHELL MESH> RECONS : cased unexpected termination if used on Frozen Macro Areas.

(in v13.0.0)

14422

SHELL MESH>RECONS : When applying reconstruction on some 2nd order shells (part meshed by Batch Mesh) the middle-nodes of not selected elements were moved to the Origin position.

9614

ELEMENTs>SPLIT>Shells : Abnormal exit in particular cases with EDGES selection. 13735

ELEMENTs>TO-SURF>[PER AREA]: fixed error caused abnormal exit (in v13.0.0) 14934

VOLUMEs>IMPROVE> RECONS : caused abnormal exit if applied on tetra mesh having more than 255 tetras per node. (in v13.0.0)

13335

VOLUMEs>EXTRUDE>TRANSLATE : the Distance was not updated by the two picked positions. (in v13.0.0)

14330

VOLUMEs>EXTRUDE>ROTATE : unaccepted results if function applied on 2nd order shell elements. (in v13.0.0)

13822

VOLUMEs>EXTRUDE> SWEEP : abnormal exit and corrupted file creation if saved. (in v13.0.0)

14083



DECKs

SETs Problem with the visibility of set contents: When having a set that contains shells from macros and do Show Only to these shells nothing is visible on screen.

13532

Renumber Unaccepted delay of renumbering during assignment of big number of elements into Include with General numbering rules.

13616

Incorrect renumbering result regarding special rules; the function should be applied twice in order to satisfy the rules.

13667

ABAQUS / ANSYS

Fixed Problem with CONTACT>FLANGES and CHECK>CONTACT ORIENTATION

10550

12614

GEB Fixed problem with the GEB_SB when it is applied in two different (mutually exclusive) parts with the same PID. The two parts had the same PID but only one at a time was active. The set builder got deactivated when one of the sub-group that contained one of the parts got disabled.

11170

CHECK Missing information in check window of "Check Model Data". Now description info is reported in check list.

10224

Checks List : Fix problems related to Highlighting selected items that are reported in the list

12370

14599

Negative volume > Fix/Orient in 2nd order elements, error is fixed 10105

Duplicate : should check 2nd order elements according to their 1st order nodes

8675

Free : 'visible' or 'whole model' blocked ansa 8904

Connectivity : did not work using PERMAS Spotwelds realization

Check Connectivity should also work when the SPRING element is not accompanied by a welding surface (MEDINA case).

8396



ABAQUS

Problem with Edge option of DLOAD : The P,P1,P2,P3,P4 labels of DLOAD for edge-based surfaces (E1,E2,...) were not valid.

DLOADs defined on Shell Edges were written with TYPE='EDLD'/'EDLDNU' instead of 'P'/'PNU'.

6820

*DSLOAD applied on *SURFACE consisting of shells is read in, but exported as *DLOAD. Also, in certain cases, the sign of DLOAD's magnitude was wrongly reversed. This is also fixed.

11991

INPUT Ranges with step different than one were not supported. Now all kind of generate options will be read in properly, without keeping the information of the generation step itself but only the true entities according the the range specification.

10118

CONTACT>FLANGES: Did not recognize contacts between CSHELLS 12614

CONTACT>INFO>NEW : Definition of CONTACT PAIR without "SURFACE INTERACTION specified was accepted. Now it is not accepted.

13215

CHECK Connectivity check reported unconnected parts, although abaqus recognized them connected

13929

If a contact set was defined as SURFACE:

CHECK>CONTACTS would report error "No master/slave set defined".

CHECK>CONTACTS ORIENTATION would report warning "No proximity...".

Those wrong error/warnings are not reported anymore.

7875

LS-DYNA

Input HISTORY : fixed problem regarding DATABASE_HISTORY_BEAM and CONTACT_CABLE_ID

12495

Output Error in output of MAT_ARUP_ADHESIVE (*MAT_169): Card 5 for this material should only be written/available when the EDOT2 field is non-zero.

13457

I/O Material angles definition for membrane shell sections:

Problem in input:In an ELFORM 9 (FI membrane) shell section due to NIP=0, ansa ignored the ICOMP and assigned ICOMP=0. Therefore the layer information was lost. Furthermore, if the user defines NIP=1, the angle B2 was ignored.

Problem in output:Although for NIP=1 ansa allowed to define both B1 and B2, in output the B2 value was not exported.

Now added "0.0" at "NIP" pulldown menu as a value.

input :" " blank field is read as zero.

output :if "NIP" is set to "0.0", B1 and b2 values are written out.

13629



if "NIP" is set to "1.0", only B1 a value is written out.if "NIP" is set to "x.0", B1, B2 ... Bx values are written out. (x!=0,1, x<=30)

D.INFO Different mass report compared with the d3hsp of ls-dyna 13884

*INITIAL_STRESS_SECTION: now allows blank VID (vector id) if the SECTION is of PLANE type / used for solids (v12.1.5)

12702

*CONTROL_SHELL : "PSSTUPD" and "PSNFAIL" changed to set types from plain integers in order to avoid their removal by the File>Compress

13768

PAM-CRASH

File>Compress Now the "Encrypted" MATERIALS and FUNCT are not removed. 13950

Input FTSS H305 v5.1s3 female dummy model:

the input of the female dummy HYBRID III 5th v5.1-s3 did not set the proper hierarchy although the *.pos (positioning) file was read!

11915

MEMBR elements were switched to SHELL if no PART definition existed in the imported file.

8289

Check Model Data: is now able to detect “Invalid Set” used for NSMAS; defined by nodes instead of elements (or Parts)

5367

Model Data: Shell materials with option curve: e.1=<blank> is now allowed

13925

Model Data: PART BEAM with MAT213 and valid "IDSEC", <blank> or zero value for "A" is acceptable.

11089

Rigid Dependency : Node related to Macro Area (geometry node) was ignored by the check regarding the usage of the RBODY NCOG as a connectivity node (used by other element)

14817

D.INFO Different mass report compared with the solver report is fixed 13884

RADIOSS

Input RADIOSS v5.1 : improper interpretation of the /UNIT keyword is fixed. 11464

Check Rigid Dependency: when a Master Node has to be "moved" out of the BOX, ANSA did not check if the candidate position fails inside another neighboring BOX



CFD++

Output CFD++ output problems related to the type of entities within the ansa file i.e. FE-model mesh or Macros mesh and ANSA Volumes mesh

(in v13.0.0)

13588

MEDINA

Wrong output of PERMAS Spotwelds with diameter=0 as Medina bif file: the diameter changed from zero to 20. In this case the diameter of the spotwelds is used as an indicator of a adhesive line.

13860

CROSS SECTION

Wrong result in Cross Section Calculation : CONN_SPOT with was not properly projected to the cross section curves. SpotLines were not properly projected to the cross curves.

9804

ANSA didn't calculate defined cross section.

Solid cross section, though was well defined (CHECK was successful), the section's values were not calculated.

10107

Boundary element distribution: The highest possible number of boundary elements sometimes was not enough to give accurate results. In addition, the distribution in complex areas was not proper enough. Now the upper limit on boundary elements is removed.

13067

SCRIPTING

LaminateLayerNew script function problem (v12.1.4) : It did not take into account the variable "NAME".

10627

GetEntityCardValues was very slow when was applied on curves 8805

CollectEntities: If CONTAINER included Macros and SEARCH_TYPE was Property (eg. PSHELL) the function did not return any property, when 'prop_from_entities' flag was on.

Fix regarding DeleteEntity script function. When deleting shells through script with the use of DeleteEntity() connection entities that referenced the shells' pid lost their representation.
