FEMAP Tips and Tricks


Siemens PLM Software


Preferences



Preferences Results – New for FEMAP 11

Automatically Attach to OP2 Files – When this option is on, OP2 results files will be “attached” instead of internalized when results are loaded from the Analysis Monitor automatically or when using the “Load Results” button

Use Memory Mapped OP2 Files – When this option is on, the “Memory Mapped File” option will be on automatically when the “File, Attach To Results” command is used. If both this option and the option above are on, then any automatically attached OP2 file will also be “Memory Mapped” (until RAM is no longer available for memory mapping)

General Solver Options and Auto Answer Post Questions – Moved to this tab from “Interfaces” tab as these options all had to do with results



Preferences Database

New for FEMAP 11.0. Performs the “cleanup” portion of “File, Rebuild” when the model is saved, so you don’t have to

do it manually to make model files smaller after deleting results

Usually, it is probably best to leave this setting alone, and remember, sometimes

it might be better to go lower, this is FEMAP’s Memory Cache

Critical for Maximum Performance – Set to a number higher than your highest

Node or Element ID

File Open/Save significantly faster. Use the “Read/Write Test” button to determine

proper setting for each machine

Can be used as a “final” option to recover data if FEMAP has exited unexpectedly during certain operations. Partial data

recovery is sometimes possible



Preferences Graphics Options that Effect Graphics Performance

Vertex Buffer Objects – Only turn this option on if you have a graphics card which supports OpenGL 2.0 or above. It has been observed that using VBOs can greatly improve performance of dynamic rotation

Max VBO MB – FEMAP will determine how much RAM is available on the graphics card, then allow you to choose how much you want to allow FEMAP to use. Typically, half of available is a safe value, but using more may improve performance without causing any issues.

Min VBO B – By default, this value is set to 1024. This value should work for a large majority of models. That said, increasing or decreasing the value may benefit certain graphics cards and/or models



Preferences Graphics Options that Effect Graphics Performance (continued)

Include in Dynamic Rotation options - switching off any these options should improve performance. • Some key options:

• Element Symbols - if you have a lot of lumped masses and springs

• Mesh Size - if you have a large number of curves with mesh sizes on

• Labels; and Undeformed - switching these off helps performance.

• Elements as Free Edges – this has a slight delay in starting and finishing dynamic rotation but dynamic rotation is much quicker. For some models e.g. a mesh on a sphere, there is no free edge and you will see nothing as the model rotates.



Preferences Example Render Setting Recommendation



Preferences Interfaces

In case you need to get to COSMOS, ALGOR, STARDYNE, etc.

Depending on how you title your Subcases, this can make sure that Output Sets get the correct names

Make sure you know where your analysis jobs are going to, especially

with Windows 7

Creates an individual group containing entities for each INCLUDE file.

“Nested” INCLUDE files will create “Referenced Groups”

New for FEMAP 11.0. Allows you to retain all INCLUDE files as INCLUDE Statements instead of internalizing the

entities in the INCLUDE file



Preferences Views – Resolution Options

Accessed via the “Resolution” button on the “Views” tab • Allows you set up default options for Printing Resolution and Copy/Save

Resolution • Additional options for Pen Width and Logo and Background Bitmap Scaling




User Interface



FEMAP Interface Model Info Pane – Expanding and Collapsing Trees

To quickly “Expand/Collapse” all sub-branches under a given branch in the tree, hold down the “Alt” key while clicking the “+/-” box

Also works when clicking a sub-branch such as “Loads” or “Constraints” or individual Load and Constraint Sets



FEMAP Interface Model Info Tree – Auto Create Load Definitions

To quickly create “Load Definitions” which only contain “loads with the same values, components, applied faces, etc.” from imported models use the “Auto Create Definition” command from the context-sensitive menu



FEMAP Interface Using the Model Info Pane to Populate Data Table

Send to Data Table icon (Only available when Data Table is open in FEMAP and “unlocked”) Useful for sending multiple entities of one type to the Data Table for comparison purposes. Great way to get elements of one shape or one type to the Data Table. Once in the Data Table use “Add Element Checks” or “Add Mass Properties” for Pre-processing or “Add Output Columns” for Post-Processing.



FEMAP Interface Model Info Pane – Activating the Layup Viewer

Fastest way to bring up the Layup Viewer for Laminates is to use the “Show” option on the Layup context-sensitive menu



FEMAP Interface Model Info Pane – Entity Visibility

Visibility Check boxes for Geometry, Elements (By Type and By Shape), Materials, and Properties Mimics the capability of various tabs in the “View, Visibility” command without having to have the large dialog box open and covering a portion of the screen In some cases, decreases the number of groups which might have been needed in the past for complicated entity selection, as screen picking (including box, circle, polygon, and freehand) now only picks from “visible entities”.

The “context-sensitive” menu is different when the mouse is positioned over the visibility check boxes and provides some useful options. Additional Options exist for Material/Property to show elements which do not reference a material or property (i.e., rigid)



FEMAP Interface Model Info Pane – Reset All Visibility Options

The Reset All Visibility Options icon in Model Info tree sets all Visibility options and check boxes back to default for new model.



FEMAP Interface Model Info Pane – Tree Scrolling – New for FEMAP 11

If the number of entities of a particular entity type exceeds the value specified for “Max Entities” preference on the “User Interface” tab, the “Next” and “Previous” markers will appear in the Model Info Tree If the cursor is placed over the “Visibility Check Boxes” and the mouse wheel is scrolled up or down, the list of entities in the Model Info tree will change dynamically Holding certain keys down changes behavior (“Max Entities” = 10): • Ctrl – Scrolls to the next “set” based on the “Max

Entities” value (i.e., 1-10 to 11-19 to 20-28, etc) • Shift – Scrolls by number of entities currently shown

in Model Info Tree (i.e., 1-10 to 10-18 to 18-26, etc) • Ctrl+Shift – Scrolls to the “last” set of entities based

on “Max Entities” (would show “last 10”) Will also work during a command for FEMAP 11.1!



FEMAP Interface Select Toolbar – Entity Visibility

Visibility options on bottom of context-sensitive menu for several entity types in the Select Toolbar.

• Graphical selection offers a more interactive method for selecting which entities should be Shown or Hidden

• Available when Solid, Region, Connector, Material, or Property is the Active Entity Type in the Selector

• Holding Shift key down while one of the above entity types is active in the Select Toolbar will bring up only the commands on the Visibility sub menu which



FEMAP Interface Select Toolbar – Accessing the Quick Access Menu

Typically, when an entity type is active in the Select toolbar, a context-sensitive menu for that entity type will appear when the right mouse button is clicked. While this is often helpful, sometimes you may need to access the “normal” Quick Access Menu (aka, Right Mouse Menu) while using the Select Toolbar. This can be achieved by simply holding the Alt key down while clicking the right mouse button.



FEMAP Interface Selection Method Shortcuts

• When using the selector dialog, keyboard shortcuts are available for several selection methods • SHIFT-LMB: Box select • CTRL-LMB: Circle select • CTRL-SHIFT-LMB: Polygon select



FEMAP Interface Selection Method Shortcuts

While the “Query” option on the “Pick^” menu in the standard entity selection dialog can be very useful when trying to select the desired entity from a list, it can also be cumbersome when selection is more straight-forward To do a “one-time” Query pick, simply change the “Pick^” method to “Normal” and hold down Alt while clicking on a particular entity. This will bring up the “Select” dialog box with entities available for selection *When the “Select” dialog box appears, you can either select an ID from the list or use the mouse wheel to scroll up and down in the list until the desired entity is highlighted in the graphics window



FEMAP Interface Advanced Picking Filters

Several advanced picking filters have been added to the entity selection dialog in the past few versions • Model Data Value • Color (Select Color from Palette) • Add Connected Fillets • Add Tangent Surfaces • Add Connected Elements



FEMAP Interface Entity Editor

A Node may be sent to the Entity Editor using the Select Toolbar or by selecting an individual row when nodes are in the Data Table View Nodal Coordinates in the model’s Active Coordinate System (set easily by double-clicking a Coordinate System in the Model Info tree).



FEMAP Interface Entity Editor

View nodal deformations in any Coordinate System by selecting a Coordinate System from “Csys for Output List” in the Entity Editor

Output Value at Node also shown when displaying Contour (Nodal Contour)



FEMAP Interface Entity Info

When open, very helpful during selection as it dynamically updates as the mouse is moved over the model (i.e., Tooltips …without the wait) Works when graphically selecting entities using the Entity Selection dialog box, Select Toolbar, or “Select” icon in the Meshing Toolbox In addition to showing the ID, great for determining: • Mesh Size on a Curves • # Nodes/Elements attached to Geometric entities • Materials with certain values • Properties with certain characteristics • Formulation and Nodes used by Elements • Definition Csys, Output Csys, and Coordinates of Nodes



FEMAP Interface Entity Info

For Post-processing, bring back “Dynamic Query” functionality from Pre-V9 FEMAP…only better, by choosing Nodes or Elements from the Select Toolbar With Nodal Contour displayed: • Nodes list the plotted output value at the node and

deformation values, if the model is currently deformed • Elements list the plotted output value at each node on the

element With Elemental Contour displayed: • Elements list the plotted output value on the element and the

values at the element’s corner nodes • Will list both “Top” and “Bottom” values when using “Double-

Sided Planar Contours” option (Contour Options dialog box)



FEMAP Interface Entity Info – Layup Editor

Laminate Equivalent Properties dynamically update in Entity Info as plies are added/removed from the Layup Editor



FEMAP Interface Entity Info and Tooltips – Version 11.1 Preview

The “Layers/Groups in Tooltips” option can be turned on via the Select Toolbar and then Group and Layer information will be shown in the Entity Info window or the Tooltip



FEMAP Interface Data Table

Automatically add Tet Collapse and Jacobian element quality checks to the Data Table for all tetrahedral elements created during tet meshing with the Mesh, Geometry, Solids command that exceed currently specified quality limits • Click “Options” button, then select “Update Data Table with Mesh Quality”



FEMAP Interface Data Table

Sort by Tet Collapse or Jacobian, turn on the “Show When Selected”, then choose rows to highlight elements of poor quality in the mesh



FEMAP Interface Named Entity Filters

Also, the “Filter” method replaces the “Search” functionality in all “Select From Library” dialog boxes

Version 10.1 and before Version 10.1.1 and after




Geometry



Geometry Parasolid Box

• FEMAP geometry uses the Parasolid kernel • Entities are contained within a Parasolid “box”

• 1000 x 1000 x 1000 box centered at the origin (+- 500 in x, y, z)

• Coincident point tolerance: 1.0e-8 • Parallel tolerance: 1.0e-11 radians

• Anything outside the Parasolid box may run into precision issues

• From the Parasolid documentation: “To allow precision to be handled correctly, all

parts of a body must be within this box.” “It is highly recommended to set the default unit

in your application code to one meter.”




Inches – Scale Factor – 39.97 • Everything entered is divided by 39.37 and stored

inside of Parasolid at 1/39.37th scale • This stores inch dimensioned parts in meters as

recommended • When using inches, this gives an effective box

size of +- 20,000 in Millimeters – Scale Factor – 1000.0 • Everything you enter gets divided by 1000.0 and

stored inside of Parasolid at 1/1000.0th scale • This stores millimeter dimensioned parts in meters

as recommended • When using inches, this gives an effective box

size of +- 500,000 mm




Scale factor is set: • When reading in a Parasolid file • In Preferences -> Geometry/Model Note that “units” used for the Parasolid box are exactly that – “units” This only affects geometric tolerancing • This does not establish a default unit in

your model • This does not have any effect on units in

material properties • This does not have any effect on units in

properties



Geometry Non-Manifold Geometry Support

Non-manifold geometry – instances where three or more surfaces share the same curve, e.g. T-junctions • Mesh will connect and match on all surfaces • Previously a limitation in Parasolid • Non-Manifold Tolerance (added for FEMAP 11.0) • Enhanced by Parasolid development team to behave

more like “stitch” for FEMAP 11.1



Geometry Non-Manifold Add

Non-Manifold Add • Not as “tolerant” as Geometry, Solid,

Stitch • Things still have to be close to 100%

coincident, only now within specified tolerance



Geometry Non-Manifold Add

Extend Past, and use Geometry, Surface, Delete to get rid of outsides



Geometry Mixed Surface and Solid Modeling

Non-manifold Add



Geometry Mixed Surface and Solid Modeling

“Subtract” Surfaces from a Solid to split solid along the surface using “Geometry, Solid, Remove” command Choose “Solid to Split” as “Base Solid”, then choose surface as the “Solid to Remove” Something to remember is that that the surface should at least extend to the extents of the solid to be split, otherwise it may not divide the solid Helpful command when sub-dividing for Hex Meshing, especially geometry has some “revolved” features



Geometry Geometry Cleanup

Parasolid BodyShop Fully Automatic Geometry Cleanup • Written/Maintained by the Parasolid Team

Data Cleaning • Detect and resolve topological problems • Invalid sense, missing topology, bad loop and region structure • Detect and resolve geometric problems • Zero length curves, short edges, coincident geometries, unwanted gaps &

spikes, sliver faces, illegal curve and surface intersections Model Optimization • Optimize models for performance and reliability in downstream use • Convert geometry to simpler forms • Recompute tolerant edges to greater accuracy • Remove small entities

Modeling / FEA



Modeling / FEA Helpful for Solid Laminates

AutoCreate option in Layup Editor – When On, automatically creates a new Global Ply as each ply is added to the Layup, which is very useful for Solid Laminates, as Global Plies are needed for proper post-processing



Modeling / FEA Helpful for Solid Laminates

Ply/Bond Failure tab in Isotropic, Orthotropic (3D), and Anisotropic (3D) dialog boxes is used to choose a Ply Failure Theory and/or and Bond Failure Theory and enter specific values for each based on the selected theory Only used by the Solid Laminate Property, which was added for FEMAP 11.0



Modeling / FEA Edge-to-Edge Contact

“Edge-to-Edge” contact for NX Nastran • Added for FEMAP 11.0 (Undocumented) • Uses the BEDGE Nastran entry and element edges or curves may be

selected when creating connection regions • Glue written for all SOLs in FEMAP (think we may not want to write it for 144-

146, 601, and 701, as those appear to not be currently supported) • Supported Element Types are CQUAD4, CQUADR, CQUAD8, CTRIA3,

CTRIAR, CTRIA6, CPLSTS3, CPLSTS4, CPLSTS6, CPLSTS8, CPLSTN3, CPLSTN4, CPLSTN6, CPLSTN8

• Contact available in SOLs 101, 103, 105, 111, 112 (XZ or XY Plane) and 601 (XZ plane only)

• Supported Element Types are CPLSTS3, CPLSTS4, CPLSTS6, CPLSTS8, CPLSTN3, CPLSTN4, CPLSTN6, CPLSTN8

• Support for Axisymmetric elements for Glue and Contact coming in 11.1



Modeling / FEA Edge-to-Edge Contact

Examples of Edge-to-Edge Glued Contact with Plate Elements (Statics – Left, Modes – Right)



Modeling / FEA Contour Model Data

Contour Model Data allows you to create a contour/criteria plot or beam diagram on the displayed elements based on any material or property value currently in your model For example, visualize different thicknesses in a shell model via a criteria plot




Analysis



Analysis Setting up Bundled / Standalone NX Nastran

FEMAP can launch bundled or standalone (enterprise) NX Nastran • Initial setup based on installation options To set up FEMAP for bundled NX Nastran • In config.ini, located in the FEMAP root directory, set

IsNX4FEMAP=1 • NX Nastran installation must be in ~\<femap root>\nastran To set up FEMAP for standalone NX Nastran • Remove the IsNX4FEMAP string from config.ini

Usually it’s easiest to simply rename config.ini • Set the environment variable NXNAST_EXE to the Nastran executable location Both of these setups will launch NX Nastran from FEMAP and will work with the Analysis Monitor




Post-Processing



FEMAP Interface New Output Selection dialog boxes for FEMAP 11.0

• Highlight any number of Output Sets then click icon buttons to (from left):

• All On • All Off • Selected On • Selected Off




Output Set and Output Vector dialog box • Output Set selection is the same as the stand-alone Output Set dialog box • Output Vectors displayed in the dialog box are based on output vectors found in the

Output Set selected using the “From Output Set” drop-down • Choose “All Output Vectors” option to select all output vectors in selected Output Sets • The “Quick Filter” can be used to quickly reduce the number of Output Vectors

displayed in the dialog box (None-Ignore, Selected Only, Node, Element, Element Centroid, Displacement, Velocity/Accel, Force, Stress, Strain, or Thermal)

• For more detailed filtering use the “Filter” button (next slide) • Highlight any number of Output Vectors then click Icon buttons to (from left):

• All On • All Off • Selected On • Selected Off

• The “Add Similar Layer/Ply Results” and “Add Component/Corner Results” buttons are used to select additional Output Vectors after at least one Output Vector has already been selected in the “Output Vectors” Section




Output Set and Output Vector dialog box (Con’t) • Optionally Filter Output Vectors by:

• Title • Output Type (Displacement, Velocity/Accel, Force, Stress, Strain, or Thermal) • Output On (Any Output, Nodes, Elements, Line Elements, Planar Elements, Solid

Elements, or User Output) • Complex Type (Any Output, Magnitude, Phase, Real, or Imaginary) • Options to include Nodal Component Output and/or Element Corner Data • Only items found in the list after being filtered will be selected with the All On option

• Use “Clear Filter” button to reset list



FEMAP Interface Select PostProcessing Data dialog - New for FEMAP 11

Select PostProcessing Data • Same Filters used in version 11 Output Selection dialog boxes can be used to reduce

the Output Sets and Output Vectors shown in the drop-down lists. • “Vector Info” can be used to view Max/Min values, Max/Min values for associated

Component/Corner Output Vectors, Vector Statistics, or Max/Min values of any additional output vector(s)

• “Section Cut” added to access options for Section Cut and Dynamic Cutting Plane



FEMAP Interface Select PostProcessing Data dialog - New for FEMAP 11

• “Dynamic Max/Min” – dynamically shows Max/Min Values with entity ID for each in the dialog box as different output vectors are selected using the drop-downs

• “Multiple Contour Vectors” – allows viewing of three different output vectors at once (i.e., Solid Stresses, Plate Stresses, Line Element Stresses in a criteria plot)

• “Double-Sided Planar Contours” – moved from Contour Options dialog box for easier access



Post-Processing Crow’s Foot Plots

2D-tensor plots, also known as Crow’s Foot plots (added in FEMAP 10.1) • Allow for quick assessment of direction of in-plane loads • Primarily used on shell elements with in-plane loads (Nxx, Nyy, Nxy) • Used most often in the aircraft industry Main advantage is to show direction of positive shear flow; sign determines actual direction

From NASTRAN: Nxx: 500 lb/in Nyy: -250 lb/in Nxy: -125 lb/in

500 lb/in

250 lb/in

• Other view options to consider… • Adjusting the arrow length to

de-clutter the screen • Set vector label digits to 1



Post-Processing Solid Non-Linear Stresses

Care needs to be taken when reviewing nonlinear solid stresses from NX Nastran • For linear static runs (101), solid stresses are output

in the material coordinate system • For non-linear static runs (106), solid stresses are

output in the element coordinate system • Output orientation needs to be specified in FEMAP

101: 0..Material Direction 106: 0..Element

Charting Pane



The Charting dockable pane was added to modernize and improve XY Plotting within FEMAP for version 11.0

Topics: XY Plotting Overview Charting Pane Overview Chart Management Data Series Management Chart Display Control Chart Output

XY Plotting with the Charting Pane



Prior to Femap v11, XY plots were created using the View Select dialog box. The Charting pane has been added to Femap v11 to manage XY plots.

Charting Pane XY Plotting Overview

Note: XY plot creation using the View Select tools are available in Femap v11 by enabling the option for Enable Legacy XY Plotting under the User Interface tab in Femap’s Preferences dialog box. This functionality will be removed in a near future Femap release.

• XY plots created in Femap prior to v11 and stored as Views are automatically converted to Charts in Femap v11.

A Femap model file can contain multiple XY plots as Charts and Data Series

Charts are defined by Data Series. Data Series are defined by Output Vectors or Functions



Display of the Charting pane is controlled by the Panes toolbar The Tools, Charting command also toggles the Charting

pane

The Charting pane’s toolbar has icons for managing Charts, Data Series, display of charts and outputting data from charts. These controls will be described in detail later in this lesson.

Miscellaneous Tips on Recovering Crashed Models

In the (hopefully rare) instance of a FEMAP crash, it may be possible to recover all or parts of your model Tips • Try to avoid this situation by saving

your model often or using autosave • Set up a scratch directory in FEMAP

preferences Things to try • Use the “Recover Scratch Directory”

button in preferences • Use the “Recover _DBData File” button to possibly recover partial data • Database and Parasolid files in the

scratch directories These tips may not always work but they do provide a last ditch option



Miscellaneous Neutral Files

Neutral files can be used to import data in a format not natively supported by FEMAP Easy to create .neu formatted files in Excel or another program Neutral file reference is located in ~\<FEMAP root>\pdf\neutral.pdf Info • Neutral files are text files containing data block and record data • Neutral files are comprised of data blocks, each starting and ending with a line

containing only -1 • Neutral files are free-formatted files • Data blocks contain lines of records that are delimited with spaces or commas

(commas are preferred)



Miscellaneous Neutral Files

Sample neutral file creating points -1

Miscellaneous Reducing Model File Size

Whenever an entity is created in FEMAP, it is stored in the database • Entities are stored in the database in groups of like entities • When entities are deleted from the model:

• The space occupied in the database by these entities is flagged as usable again • The database is not truncated to reclaim that space

• Reclaim this space using the File -> Rebuild command

• Commit by saving the model

• Can now be done automatically during save by using “Cleanup During Save” option found on the Database tab of “File, Preferences”
