Fixed Bugs

CSAM-488 POLYFLOWLib was reading all files with “res” in their names

The Polyflow reader was processing all files with “res” in their name instead of checking that the extension was “.res”.

CSAM-480 H3D file fails to open because of pool name IDs mismatch

The H3DLib failed to open files whose results data sets were not associated with any elements. These results are now ignored.

CSAM-489 Fix PERMASLib crash while loading complex values

The PERMAS file reader crashed when processing complex results data, depending on compilation settings.

CSAM-271 Fix bad jump on uninitialized node degree value

Fix undefined behavior during quad meshing in SurfMesh.

CSAM-478 Fix ANSLib Cyclic Symmetry Duplicate Mesh sets

Fix ANSLib Cyclic symmetry case with Duplicate Mesh.

In case of Cyclic symmetry, the result file may contain a duplicate mesh needed and generated by Mechanical.

The elements of this duplicate mesh are obtained by an unknown but constant offset of the Base element indices. This offset was not correct for elements assuming an odd/even sorting.

CSAM-463 Manage error in vis_SurfMesh while meshing with coarse quads

vis_SurfMesh could crash when meshing with quads due to an issue in meshing failure management.

CSAM-448 Wrong surface name written in *COUPLING Abaqus card

The Abaqus input file writer ABAFwt could use a surface name in the *COUPLING card that was defined in the file.

CSAM-454 Unable to read vendor specific elements when an Adina op2 is loaded

The NASlib reader was not able to read some vendor specific element types when an Adina result file was loaded.

CSAM-288 Resolve MPC circular dependencies in the solver

MPC circular dependencies are automatically managed in the solver to avoid singularity issue.

CSAM-485 Fix CGNS export when model contains Polygons but no Polyhedron

When a model contains only surfaces, there is no polyhedron in the model, and the exported mesh not was correct.

CSAM-484 Fix CGNS Poly export when no Polygon in model

Fix CGNS export when there is No Polygon in the model.

This may happen as instance when the convention VDM_CONVENTION_WALLINTER is not set during the Fluent import.

CSAM-481 OpenFOAM reader fails to read polymesh files which are in result folders

Polymesh files located outside the “constant” directory were not processed.

CSAM-476 Fix ABAFwt distributing coupling surface names and exported weights

An exported Abaqus input file may contain invalid *COUPLING cards because they may be applied to a surface whose name was defined twice for two different surfaces definition. Furthermore, some coupling weights may not be exported with their expected values but with a default value of 1.

CSAM-400 Fix Op2 unexpected dataset S.[VONMISES] when no corresponding OES data table is there

In NASLib_library device, if all the element types having von Mises stress or strain values are EL (Element node), if there is only 1 ecode element type having centroid value and no von Mises value, an unexpected dataset S.[VONMISES].E full of 0.0 was created.

CSAM-439 Fix CGNS export Polyhedra NFACE_n connectivity

When writing Polyhedra face connectivity NFACE_n and if polygon elements are numbered with higher values than polyhedra, the wrong entry in NGON_n was used.

CSAM-440 Fix bug on contour.c to output the right contour plot with ISOVALTONE

A bug has been fixed on contour.c to output the right contour plot with ISOVALTONE.

CSAM-271 Fix connect PlaneIntersect signature function on C# wrapper

Function PlaneIntersect had the wrong number of attributes.

CSAM-291 Fix misleading documentation on VolMesh

VolMesh is not currently able to produce hexahedra or wedges. VolMesh produces pyramids from the quadrilateral faces provided and tetrahedra from the triangular ones. Finally, it fills the remaining volume with tetrahedra.

CSAM-424 Fix datasets related to effective mass in NASLib

EFFECTIVE_MASS.T, PARTICIPATION_FACTOR.T, MASS_FRACTION.T and EFFECTIVE_MASS_SUMMARY.T datasets were stored as float, but the data was read as double, leading to memory allocation issues.

CSAM-436 Fix out-of-bound issue in Prosolve due to missing reallocation

Use of MPCs in ProSolve may lead to a memory allocation issue if the number of MPCs was increasing during the simulation.

CSAM-412 Fix automatically sorted node labels while writing sets in the ABALib writer

Fix automatically sorted user node IDs while writing an odb file. If the node labels are sorted, the data is no longer linked to the right node. For example, for indexes 1->10 if the user node IDs are 10, 1, 2, 3, 4, 5, 6, 7, 8 and 9; the nodal data from node index 10, user ID 9 was printed as assigned to the node of index 1, user ID 10 because of the reordering.

CSAM-397 Fix crash in FEMap reader for beam/shell results

This fixes a crash in FEMap reader when no shell or beam has been read in the model but a shell or beam related result is detected.

CSAM-411 Avoid ABALib crash while writing an odb without part Ids defined

This fix avoids an ABALib crash while writing an odb without partIds defined, and a meaningful warning has been added (pointing the partner to the VDM_CONVENTION_ALTPART convention).

CSAM-404 Fix ABALib odb writer for nodal data leading to huge memory consumption

When nodal data with written and no consistent node was found (i.e., if data is written for a subset of nodes), a large memory consumption could be observed.

CAE-911 Fix deallocation of variables faceSharingThreads, and adjacentsElements in CGNS converter

Fix memory issue during CGNS file export when Polys are written.

CSAM-382 ABALib reader crashes when releasing step memory with odb APIs older than the 2022 release

The third party odb API is failing to release step-related memory in APIs older than 2022.

CSAM-394 Fix relative order between GL_VERSION_3_0 and OGLVERBEG(30) in vgl

Fix relative order between GL_VERSION_3_0 and OGLVERBEG(30) in vgl that were producing compilation error.

CSAM-376 Op2 datablock read OES1 as OES1C with Composite elements

Fix Nastran op2 import of OES1 data block for composite element type:

QUAD4_comp(eltype=95), QUAD8_comp(eltype=96), TRIA3_comp(eltype=97), TRIA6_comp(eltype=98),

QUADR_comp(eltype=232), TRIAR_com(eltype=233)

CAE-1088 Fix reading PARTIDs of an Ansys rst file in ANSLib

Fixed an issue related to the PARTIDs. Some parts of a model were merged into a single part called Part0 which has an invalid PartID.

CSAM-331 Remove print statements from comsollibio.c

Remove print statements from comsollibio.c

CSAM-287 Manage “ghost” elements in Ansys rst files

This fix helps ANSLib managing “ghost elements” in Ansys result files without crashing: sometimes, N elements are supposed to be defined in the result file, but a small fraction of them has no element identification as if they disappeared.

CSAM-330 Fix extension parsing of comsollibio

strstr was being used to parse the file extension of files in the “Open” method. Since strstr returns the first value that it reads, files were always being interpreted as binary if the filename contains both mphbin and mphtxt sub strings.

CSAM-288 MPC management fixes in Access

Various improvements/fixes made while investigating MPCs management:

  • Solve use-after-free issues after vdm_LibraryEnd.

  • Fix SYS_SOL_SUPERELEMENT-based Nastran input file generation in NASFwt.

  • Manage 0 eigenvalues requested in *FREQUENCY Abaqus card in ABAFil.

  • Fix weight management for non-uniform weights in ABAFwt.

  • Add METHOD case control to select eigenvalue extraction parameters in NASFil.

CAE-1085 - Uninitialized variable for multiple scalars in SDRCLib dataset 2414 + fix user defined temperature conversion factor reader

  • Add support of all scalars in the datatype to avoid uninitialized variable in the 2414 dataset.

  • Fix storage of the custom temperature factor (should be 1/data read).

CAE-985 vis_State reports undefined stress tensor for shear panel elements

The tensor results reported through vis_State is undefined for shear panel elements.

CSAM-285 Exported date is corrupted in NASFwt when locale is set to fr_FR.UTF-8

Fix NULL termination issue when the exported date is longer than 11 characters.

New Features

CSAM-335 Support Ansys 2023R1

Current release support ansys file 2023R1.

CSAM-447 Support Abaqus odb API 2023

The Abaqus odb API 2023 is now provided with the library.

CSAM-271 SurfMesh performance improvement 2

Metric computation is a very expensive operation happening during meshing, this computation has been specialized for different element shapes, so it has less overhead

CSAM-271 SurfMesh performance improvement 1

Improve iterative point projection algorithm to avoid repetitive constant computations on every iterations.

CSAM-475 Export CGNS: add Convention to use old Cell zone formulae

A new convention VDM_CONVENTION_CGNSLEGACYCELLZONENUMBER is added to be able to use the old formulae when exporting the Cell size with cg_zone_write: Old: size[0]=Cells number + surface elements number + number of surface elements generated to describe polyhedra.

CSAM-396 Store the default FEA element technology used by ProSolve if not initially defined

Store the FEA technology in the Connect if a default FEA technology needs to be set in the solver. Before this fix, only the default FEA technology of 3D solid elements in a structural analysis would be set in the connect while solving. This fix restores a consistent behavior.

CAE-985 Add shear panel stress dataset for SOL101 shear panel elements

A scalar stress dataset with the SHEARPANEL qualifier is added for Nastran SOL101 shear panel elements (ecode 4).

Since the stress data was already being reported, removing it would be a breaking change. To solve this issue, the convention VDM_CONVENTION_ONLYSCALARSHEARPANELSTRESS was added. When this convention is added, the stress of shear panel elements is reported as undefined in the tensorial representation.

CSAM-387 Add Convention VDM_CONVENTION_CGNSALWAYSMIXED for CGNS format export

A new convention VDM_CONVENTION_CGNSALWAYSMIXED is added to let the user able to enforce the MIXED type while exporting sections of the model every time a section contains only 1 type of elements.

CSAM-336 Read shell offsets from the vis_Model

Add vis_ModelElemOffset() utility function to get shell offsets, based on vis_ModelElemThickness().

CAE-985 Add scalar view of stress for shear panel elements

Present the stress as a scalar dataset for elements of the shear panel type. These elements can only have in-plane shear stress. Whenever a shear panel element is detected, we create an additional data set with the SHEARPANEL qualifier. If the vis_State is used, data is reported as defined only for shear panel elements.
