BETA-CAE Systems 23.1.1

BETA CAE Systems 23.1.1 release notes - Date: March 22, 2023


Known issues resolved in ANSA

GUI
Real time performance upon mouse-hovering is now achieved. A representative example is the acceleration in the "Dynamic" selection mode of the Measure.
CAD Import/Export
Regarding Input model definition, the performance of parsing JT files has been accelerated to half the operating time.
Moreover, in case of consecutive runs of CAD to ANSA process, an erroneous indication for the currently alive runs might have led to partially incomplete translations.
Modular Run Management
The Lifecycle Graph for Simulation Runs would not be correctly drawn in cases of links based on the history links of the contained Simulation Model and Loadcase.
TOPO
The creation process of Curves could lead ANSA to freeze, when "Draw shell as solid" was activated.
Shell Mesh
Abrupt termination could occur when Quad element type (Pattern [4-Sided]) was applied on a macro area with neighboring unmeshed and frozen macro areas.
Regarding 4-Sided Patterns, significant improvement on preserving the initial curvature of FE surface mesh while remeshing, has taken place.
Volume Mesh
As for the Structured Mesh and, specifically, Extrude [Offset], the function would produce duplicate elements when the "Both sides" option was used for Direction.
As for the Volumes and specifically for Conv2Poly function, negative Volume elements would be generated at the interface between Unstructured and Structured Mesh.
DECKs
ANSA could cease to respond during input of LS-DYNA solver files that contained both ANSA and FATXML comments.
Focusing on Results Mapper, unexpected termination could occur during the mesh alignment when manual positioning, interactive manipulation, of source data for a USER format file.
Concerning Renumber [Edit], unexpected termination would occur in Abaqus and Pam-Crash solver interfaces.
ECAD Importer Plugin
The performance of trace mapping is now significantly improved. An overall acceleration of up to 5 times has been tracked for typical ECAD cases.

Known issues resolved in EPILYSIS

Performance
A significant speed-up has been achieved in cases where multiple RESVECS were requested. In specific, requesting RVDOF in 900 DOFs, the overall time was reduced from 2h:40m to 25m.
Calculation
EPILYSIS would stop operating in case of NSM on 2nd order shells with deleted nodes.
Furthermore, unexpected termination would occur in machines with very large memory, when "IN ANSA" option was used to run the solver.
SOL200
Unexpected error would occur in the sensitivities' calculation of an MFREQ subcase with zero load.

Known issues resolved in META

Read Results
"Time" abscissa for transient results in .h5 files would not be read correctly.
Geometry from .nas files could not be read on Windows OS, whereas strain scalar results from NX-Nastran were not read properly.
Unexpected termination could occur when reading ParaView VTK files.
More cases, focusing on LS-DYNA:
- Cross section planes would not be transformed properly, whereas vector tensor results for solids would not be read correctly.
- Results from binout files with double precision would not be read as expected.
- As for FEMZIP, META would cease to respond when switching to Results tab, in case of adaptive remeshing.
TAITherm
META would hang when reading geometry results from files located on network drive on Linux OS.
NVH Calculators
Focusing on FRF Assembly, in case the TPA input files for forces and transfer functions contained data at 0Hz with zero values, connection forces, transfer functions, and point mobilities were not displayed for any frequency.
Regarding Modal Response, Structural Modal Participation Description settings were wrongly taken from the corresponding fluid participation settings instead of the structural and Modal Response results in normal direction. Now they are correctly calculated in both 2D Description and 3D labels.
File Export
Saving curves in ISO TS13499 format was not operating properly in versions 23.0.x and 23.1.0.
Failed elements were not saved as expected, when exporting a .d3Description file.
Erroneous values for Rigid Elements were written during output of Stress results in .unv files.
Project Files & METADB
Calculation of Major Principal Strain result for solid elements was not correct when the primary Strain results were stored in a METADB file.
Data Management
It was not possible to read geometry from a METADB file.
User Toolbars
Toolbar packages generated from the BETA Packager Installer would not work properly, due to changes in how META executes Python scripts through the "read session" command. .
As for the Topology Optimization Toolbar, geometry from .h3d files would not be successfully read.

Known issues resolved in KOMVOS

Modular Run Management
During import of solver keyword files such as Subsystems or rich Library Items, the DM header section might erroneously fail to be added or updated.
SPDRM client
KOMVOS would fail to connect to an SPDRM server through HTTPS, in case SSL was enabled on the server.
Machine Learning
Mode Classification would not be possible for Simulation Runs of result files with different names.
Script Editor
Functions help was not available in a KOMVOS instance of a full BETA Suite installation.
