Enhancements and known issues resolved in ANSA

Known issues resolved in ANSA

CAD Import / Export

Upon translation of CATIA files, by enabling the option Hierarchy [Force single part], the structure of the Geometric Sets would be erased, resulting in erroneous input of geometry.

Modular Run Management

Focusing on Interface and particularly on A POINTs / LC POINTs, when creating a new Assembly or Loadcase point on location, the selection of a user defined area would not be stored. As a result, the Assembly/Loadcase point would fail to be applied.

Moreover, It would not be possible to change the position of an Interface Point through the entity card (i.e. x,y,z values), once applied.


In Batch Meshing domain, the batchmesh.ReadSessionMeshParams() script function would not read wrap parameters correctly.

In DECKs, the "Mass Information" result of the script function base.DeckInfo() would ignore elements related to MAT_NULL, leading to erroneous result.

Enhancements and known issues resolved in EPILYSIS

Known issues resolved in EPILYSIS


When STRESS and FORCE header command had a reference to a SET of Superelements, internal elements results would erroneously be printed for all elements.

Enhancements and known issues resolved in META

Known issues resolved in META


Unexpected termination could occur when adding connected PIDs, while multiple pages existed.

In Graphics, activating the option "Draw only Min/Max Tensor Components" did not have any effect, apart from the fact that Fringe range was not properly calculated for free grids.

Read Results

Several fixes for various solvers have taken place, as follows:

- The center of gravity was generally not calculated correctly.

- After CTRL+N, the setting for the surface option when reading stresses from NASTRAN files was not updated and led to reading of wrong results.

- OptiStruct modal participation factors were not recognized correctly from HDF format and a contribution analysis could not be performed. In addition, META would unexpectedly terminate, when reading modal or panel participation results from OptiStruct punch file.

- Reading ParaView .vtk files of certain format would lead to frozen state.

- Patran template file was not respected and this led to erroneous loading of results.

- Global curves (Energies, etc.) could not be read from Pam-Crash result files.

- In case of FEMZIP .d3plot files, initial results were not removed, when "Stresses minus Initial" results were loaded.

- As for the Template Manager, unexpected termination could occur while reading Strain Energy, Inner Surface results.

Managing Curve Data

Modal Displacements 2d result could not be read correctly for all the subcases, while reading a Nastran .pch file.

NVH Calculators

After a successful FRF Assembly calculation, an unexpected META termination could occur when trying to calculate twice a modified FRF Assembly setup which had errors in the Full check and was error-free in the Assembly check.

In Modal Response, when complex modes with zero real part were provided, calculation was interrupted, complaining for zero eigenvectors.

Session - Scripting

When script function session.Quit() was invoked, even though the termination of the application was scheduled, the execution of the python script would continue after the session.Quit() statement.
