IMPROVEMENTS

Mesh evaluation

It has become possible to calculate the eventual mesh size before Compute operation. For this, select the mesh in the Object Browser and select Mesh � Evaluate main menu item.

This functionality allows avoiding potentially time-consuming calculations.

The result of evaluation will be displayed in the following information box:

Duplication of Elements

The Duplication TUI functionality has been extended to provide a real model of a crack, i.e. a mechanical defect of width equal to zero. So, the duplication now works with 2D and 3D mesh elements (edges and faces).The behavior of the algorithm is shown in the pictures below

The location of the crack

including nodes and edges is shown in bold.

The elements to be replicated, including nodes and edges are

shown in red.

New algorithms and hypotheses for quadrangular meshing

New Radial Quadrangle 1D2D algorithm applies to the meshing of 2D shapes under the following conditions: the face must be a full circle or a part of circle (i.e. the number of edges is less or equal to 3 and one of them is a circle curve). The resulting mesh consists of triangles (near the center point) and quadrangles.

This algorithm requires the hypothesis indicating the number of mesh layers along the radius. The distribution of layers can be set with any 1D Hypothesis.

A Disk meshed with Radial Quadrangle 1D2D algorithm

A triangle meshed with Quadrangle (Mapping)

algorithm

It has become possible to mesh faces built on 3 edges with Quadrangle (Mapping) algorithm.

In this case mesh construction requires the new Quadrangle Parameters hypothesis, which allows indicating the base vertex at a top of the face, which will be surrounded with triangles.

Another application of Quadrangle Parameters hypothesis consists in the meshing of segments of circle.

If the meshed segment is built with angle exceeding 180 degrees, it is especially important to correctly choose the base vertex.

Custom Presentation of Vertices

It is now possible to customize the presentation of vertices in OCC viewer. For this, select the vertex or several vertices (with Shift button locked) in the viewer or in the object browser and select Point Marker item in the context menu.

The following dialog box will appear.

It is possible to choose one of the standard vertex shapes and its scale, or ...

... to define a custom texture for the selected vertices.

Fillet 1D

Fillet 1D operation allows creating fillets on the corners of a Wire with Planar Edges.

Each couple of edges connected with a vertex, where 1D fillet should be constructed, should lie in the same plane.

To produce a 1D Fillet on the selected wire, in the main menu select Operations � Transformation � Fillet 1D item.

Select the Wire with planar Edges to create a fillet on, point the necessary vertexes on this wire in the OCC Viewer and specify the radius of the Fillet.

Building a point on curve/surface by projection

It has become possible to build a point on a curve or surface by specifying its X, Y, Z coordinates. The result is a projection of the point with given coordinates on the given edge or face. If the point specified by the coordinates does not lie on the edge or face, the projection algorithm finds the point closest to the specified coordinates.

The actual vertex (30; 30; 0) is shown in yellow color; its resulting projection to the edge is in purple.

Closed Interpolation Curves

It has become possible to build closed interpolation curves from a set of points.

To produce this type of curve, check Build a closed edge checkbox in the “Interpolation Curve” creation dialog box.

Non-closed curve Closed curve

Fixed Points 1D Hypothesis

A new Fixed Points 1D meshing hypothesis allows splitting edges through a set of points parameterized on the edge (from 0 to 1) and a number of segments for each interval limited by the points.

Same Nb. Segments for all intervals checkbox allows defining the same number of segments for all intervals.

The splitting direction is defined by the orientation of the underlying geometrical edge. Reverse Edges list box allows specifying the edges for which the splitting should be made in the direction opposite to their orientation.

Mesh with normal orientation of all edges

Mesh with one reversed edge

Mesh Group Labels

The group names are now shown by text labels in the top-right corner of the viewer in Post-Pro and Mesh modules.

The preferences for this feature can be set in the following section: SALOME � Viewers � VTK Viewer 3d � Names of groups.

Shrink Factor

A possibility to modify the Shrink Factor (from 0 to 100) of the selected presentations has been introduced in the 3D-viewer via context menu command Properties � Shrink Factor of Post-Pro module.

A higher Shrink Factor corresponds to a greater size of shrunk mesh elements.

In the picture you can see box cells visualized with the Shrink Factor equal to 60.

Cut Segment Presentation

A new Cut Segment presentation type has been introduced in the Post-Pro module. This is a simplified variant of Cut Lines presentation, used to specify a single line instead of set of lines. The axis of the line is defined by the coordinates of two points in a 3D space.

Evolution On Point Presentation

A new Evolution on Point presentation type has been implemented in the Post-Pro module. This feature allows tracing temporal evolution of a variable at the given point. It can be activated by Evolution on Point item the in context menu on the field.

The availability of this operation in the context menu depends on the following conditions:

• The selected field should be defined on the Node entity.

• The field should have several (>1) time stamps defined on it.

Evolution of selected point

YACS module evolution

• New features in GUI of YACS module:

o Creation of a ForEachLoop Node of any input type.

o Creation of an OptimizerLoop Node is now possible in the GUI, with several new options on the optimization algorithm.

o In a Python Node, the Python script is validated in edition mode (via compilation).

o SALOME Service Nodes can be created either in a new component instance, or in an existing component instance: the user selects default behavior in the preferences, and still has the possibility to change the behavior at each node creation.

o Properties associated to the links, nodes, containers and components are now editable in the GUI (as dictionary of strings in a table widget).

o User Catalogs can be automatically loaded with YACS.

o A new DataRef type is proposed for reference exchanges between nodes.

In addition, it is possible to specify the number of sub-segments to be generated for each resulting edge segment. Summary: EDF 1042 SMESH : GUI of SMESH hypothesis not multi-study? Improvement: The mechanism of hypothesis creation in SMESH has been modified to create hypotheses when they are required instead of storing them in a map. This allows avoiding errors on simultaneous creation or edition of hypotheses of the same type. Summary: EDF SMESH 1047: Impossible to select pentahedrons when creating mesh volume groups Improvement: ConvertToQuadratic() and convertElemToQuadratic() methods of the SMESH_MeshEditor class have been corrected to take into account the elements containing 5 nodes (previously, only the elements with 4, 6 and 8 nodes were processed). Summary: EDF 1046 SMESH: Revolution of a 2D quadratic mesh leads to bad mesh Change: Revolution of quadratic 2d mesh elements has been implemented for the cases where one or two nodes lie on the axis of rotation. Summary: [CEA 341] SUPPORT::makeMesh() Change: MEDMEM::SUPPORT::makeMesh() method has become generic – all types of elements are now taken into account. Summary: EDF 1020 SMESH : Radial Mesh of a cylinder Improvement: It has become possible to use a new "RadialQuadrangle_1D2D" hypothesis for 2D mesh creation for faces built on a circle or a part of circle. The resulting mesh will include several triangles near the circle centre. Summary: EDF 695 SMESH : Improvement of DoubleNodes TUI feature Improvement: The algorithm of node duplication providing simulation of cracks has been modified to be able to duplicate faces and edges, not only nodes as in the previous implementation. The lower-level elements of the duplicated element (i.e. nodes of an edge) are cloned automatically.

VISU MODULE

Summary: EDF 593 VISU : min and max scalar map of results given at gauss points New Feature: "Gauss Metric" option has been added to the dialogs for "Scalar Map" and "Deformed Shape" presentations. It is active when the result is based on multiple gauss points and allows choosing which value will be extracted from the Gauss Points data – average, minimum or maximum. Summary: EDF 874 VISU : Visualize evolution of a variable at a given location New Feature: A new “Evolution on Point” presentation type has been implemented in the Post-Pro module. This feature allows tracing temporal evolution of a variable at a given point. It can be activated by 'Evolution on Point' action in context menu on field. Summary: EDF 954 VISU : Constant field with Gauss points Improvement: Now the presentations in Post-Pro are built with a certain precision that can be defined in module preferences "Representation" -> "Floating Point Precision". This precision is also used for dialog box fields and for "Values Labeling". Summary: EDF 957 VISU : shrink gauss points Improvement: It has become possible to change the rendering mode for Point Sprites and OpenGL Points from opaque to transparent in the dialog available from "Properties - Opacity" context menu. Summary: EDF 972 VISU : Shrink coef Improvement: A possibility to modify the Shrink Factor of the selected presentations has been introduced in the 3D-viewer via context menu command "Properties/Shrink Factor".

Summary: [CEA 347] Long name management from GIBI driver Improvement: Reading and writing of GIBI drivers have been improved to save real MED names of groups, fields and field components in a GIBI file and to restore them from it. This information is written in a GIBI file as a string section (PILE 27) and three tables (in PILE 10): MED_MAIL for meshes, MED_CHAM for fields and MED_COMP for components. The tables MED_MAIL and MED_CHAM set the correspondence between MED names, stored in the STRING section, and short GIBI names, stored in MAILLAGE and FIELDS sections. The table MED_COMP sets the correspondence between MED names and short GIBI names of components, both stored in the STRING section. The naming of components in a sauv file has also been modified: earlier the names containing 8 or less symbols were written as is and others were truncated, now the names of components containing 4 or less symbols are written as is and others are replaced by "Cxxx", where "xxx" is a number. Summary: [CEA 349] P1P0 barycentric interpolators. Improvement: A new P1P0 interpolator for 2D, 3D Surf and 3D (structured/unstructured), which uses barycentric coordinates instead of dual meshes, has been implemented in INTERP_KERNEL. Summary: [CEA] miss configuration between MEDSPLITTER and boost Change: Boost flags have been added to MEDSPLITTER_Swig makefile for correct compilation (only for V5.x). Boost status has also been added to MED configuration report (both V5.x and V4.x). Summary: [CEA] sauv2med : bad conversion Change: The algorithm of conversion of GIBI fields with sub-fields has been modified to produce a valid MED file. Summary: [CEA 354] attribute initialization missing in copy constructor of MEDMEM::MESH Change: Copy constructor of MEDMEM::MESH class has been improved to initialize all necessary class fields. Summary: [CEA 353] sauv2med : adjustment of Cast3M writing error Improvement: It has become possible to read badly written real numbers (numbers without the necessary "E" or "e" letter) from SAUVE files. Additionally, "C" locale has been set for reading of real numbers from SAUVE files to fix the case of user locales with another numeric format. Summary: [CEA 355] integration of RENUMBERING tool Improvement: A renumbering tool has been added in MEDMEM. It is an executable transforming poorly numbered meshes (FLICA-GUI type ones, for instance...) into more coherently numbered ones. This way, the codes converge much faster on these meshes. Summary: [CEA] Groups in a mesh obj not written in MED file when mesh contains only polyg/polyh elements Changes: In MEDMEM, the problem with reading groups of a mesh containing only polygons has been fixed.

KNOWN PROBLEMS AND LIMITATIONS • The following modules have not been migrated to Qt series 4 and thus are not included into

SALOME 5.1.3 release: FILTER and SUPERV.

• The following limitations refer to BLSURF plug-in:

o Mesh contains inverted elements, if it is based on a shape, consisting of more than one face (box, cone, torus...) and if the option "Allow Quadrangles (Test)" has been checked before computation.

o SIGFPE exception is raised after trying to compute a mesh based on a box with "Patch independent" option checked.

o It has been found out that BLSURF algorithm can't be used as a local algorithm (on sub-meshes) and as a provider of low-level mesh for some 3D algorithms because BLSURF mesher (and, consequently, the plug-in) does not provide information on node parameters on edges (U) and faces (U, V). For example, the following combinations are impossible:

� global MEFISTO or Quadrangle(mapping) + local BLSURF;

� BLSUFR + Projection 2D from faces meshed by BLSURF;

� local BLSURF + Extrusion 3D.

• Sometimes regression test bases give unstable results; in this case the testing should be restarted.

• A native VTK can be used only after manual recompilation with the GL2PS component.

• NETGEN 1D-2D and 1D-2D-3D algorithm do not require definition of 2D and 1D algorithms and hypotheses for both mesh and sub-mesh. 2D and 1D algorithms and hypotheses defined with NETGEN 1D-2D or 1D-2D-3D algorithm will be ignored during calculation.

• SALOME supports reading of documents from earlier versions but the documents created in the new version may not open in earlier ones.

• If SALOME modules are not installed in a single folder, SALOME may not work in the CSH shell since the environment variables are too long by default. In this case, it is suggested to use SH or to install all modules in the same folder.

• During the compilation of OCT 6.x by makefiles on a station with NVIDIA video card you can experience problems because the installation procedure of NVIDIA video driver removes library libGL.so included in package libMesaGL from directory /usr/X11R6/lib and places this library libGL.so in directory /usr/lib. However, libtool expects to find the library in directory /usr/X11R6/lib, which causes compilation failure (See /usr/X11R6/lib/libGLU.la). We suggest making symbolic links in that case: “ln -s /usr/lib/libGL.so /usr/X11R6/lib/libGL.so ln -s /usr/lib/libGL.la /usr/X11R6/lib/libGL.la”.

• VISU module does not support timestamps defined on the same field but on different meshes

• Stream lines presentation can not be built on some MED fields due to limitations in VTK.

• MEFISTO algorithm sometimes produces different results on different platforms.

• In some cases the number of triangles generated by MEFISTO may de different at each attempt of building the mesh.
