BETA CAE Systems Releases ANSA, EPILYSIS, META Suite and KOMVOS v21.0.2

LUCERNE, Switzerland, Jan 8, 2021 – BETA CAE Systems announces the first bug-fix release of ANSA/EPILYSIS/META and KOMVOS v21.0.x series, version 21.0.2. Apart from fixes in the detected issues, this version also hosts noteworthy enhancements and implementations.




Known issues resolved in ANSA


ANSA would terminate unexpectedly by pressing the exit button on the License confirmation window, after the execution of kill user command.

Data Management

DM Browser poor performance could be detected when opening the Reports Table for several DM items containing many attached Reports, when SPDRM was the back-end. After performance improvements, Reports Table activating speed has been accelerated by 4-5 times.

Modular Run Management

In case more than one manual Loadcase Headers were saved in DM, only the one that contained the current Header would be saved correctly.

Shell Mesh

Auto CFD spacing and CFD meshing functions have noticeably accelerated execution speed.

Volume Mesh

Unexpected termination might occur when the function Extrude [Revolute] from the Structured Mesh menu produced more than one volumes, according to Connectivity, PID or Part of the source area.


Unexpected termination could occur when ICFD_MATERIAL was selected to be reported at D.INFO report.

For more details about the new software features, enhancements and corrections please, refer to the Release Notes document.

Known issues resolved in EPILYSIS


EPILYSIS would produce misleading results due to erroneous unit-related operations, such as fluid-structure coupling cases or MNF calculation when specific unit abbreviations were specified.

For more details about the new software features, enhancements and corrections please, refer to the Release Notes document.

Known issues resolved in META

Read Results

The reading performance of META has been significantly boosted in numerous cases, such as FLUENT .dat result files, Animator databases of models with many RBE elements or simply PIDs from the new Converge .h5 format

NVH Calculators

Spotting on FRF Assembly, unexpected termination could occur when deleting and recreating a component, while keeping the same name.

Furthermore, in certain cases where Linear Combination nodes were used as responses, calculations could be incorrect, depending on the included Loadcases.


Reading “Volume Fraction” scalar results of Fluent .cdat files would lead to unexpected termination.

Project Files & METADB

Unexpected termination would occur when saving META project, in case functionality relevant to annotations attributes had been applied, whereas annotations had been copied among models.
