the v21.1.6 of its software suite

About this release

v21.1.6 arrives as the culmination of our efforts to provide error-proof mechanisms that will safeguard your customization operations and tasks in v21.1.x series.

This last bug-fix release for ANSA/EPILYSIS/META and KOMVOS hosts numerous fixes in recently detected issues, a highlighted selection of which is featured below:

Known issues resolved in ANSA
Known issues resolved in EPILYSIS
Known issues resolved in META
Compatibility and Supported Platforms


Known issues resolved in ANSA

CAD Import / Export

Thanks to the new library of CT 2021 SP3, unexpected termination regarding SolidWorks and CATPart files has been avoided and special cases with missing color information in CATIA have been successfully addressed. These bug-fixes come to supplement, on top of the existing ones, the support of the following formats:
- NX CR 1980
- Creo 8
- Parasolid 33

CAD to ANSA Translators

Translation per folder via the –idir option would not succeed in acquiring license for CATIA v4 files.

Data Management

ANSA could terminate unexpectedly when adapted Subsystems or Group Subsystems that contain adapted Subsystems were saved in DM.


Unexpected termination would occur due to erroneous definition of not Applied A_POINTs entities or when GEB [GEB_GN] entities were attached to Rigid material.

Optimization Tool

The creation of the session file for a DOE study, through the Post-Processing task item, would not be successful for other than EPILYSIS and Nastran solvers.


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


Known issues resolved in EPILYSIS


WEIGHTCHECK/GRDPNT would not be calculated correctly in SOL101 case with DMIG (M2GG).


Unexpected termination would occur in SOL110 with EKE output request.


Unknown conflict would occur in case of ANALYSIS=DFREQ/MFREQ with adjoint response and structural damping.

Moreover, EPILYSIS would terminate with an error, if USET GRID for MDEXPORT was referenced in an SPC, even if the USET DOF and the SPC DOF were different.


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


Known issues resolved in META


Deleting a window while animating would cause unexpected termination.


Shape Optimization results from .op2 files for mode optimization would not be read correctly.


Unexpected termination could occur when plotting curves of Shell Strain output from binout files.

Read Results

PIDs would not be read correctly in .h5 format from conjugate heat transfer Converge cases, and in Patran formats with 8-digit ID.

NVH Calculators

OptiStruct FSI DMIG would not be successfully read in Modal Response.

Fluid structure coupling calculated by META would couple two parallel structural panels instead of just one, if the cavity free surface was positioned between these two panels.

Modal Response & FRF Assembly: In Fraction (Polar) Plots, the Range Type setting would not be respected.


Memory leak could occur when using thr script function results.StartChangingCentroidScalar().


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


Compatibility and Supported Platforms

ANSA files saved by all the first and second point releases of a major version are compatible to each other. New major versions can read files saved by previous ones but not vice versa.

META Project files saved from version 21.1.6 are compatible and can be opened by META version 16.0.0 or later.

Support for Mac OS has been discontinued.

Support for 32-bit platform has been discontinued for all operating systems.

What to download

All files required for the installation of this version reside in the folders named "BETA_CAE_Systems_v21.1.6" and are dated as of February 10, 2022. These files should replace any pre-releases or other files downloaded prior to that date.
The distribution of this version of our pre- and post-processing suite is packaged in one, single, unified installation file, that invokes the respective installer and guides the procedure for the installation of the required components.

For the installation of the software on each platform type, download from the respective folders, the .sh file for Linux or the .msi file for Windows.

In addition to the above, optionally, the META Viewer is available to be downloaded for each supported platform.

The tutorials and the example files reside in the folder named "TUTORIALS". This folder includes the complete package of the tutorials and example files, and a package with only the updated ones.

The Abaqus libraries required for the post-processing of Abaqus .odb files are included in the installation package and can be optionally unpacked.

Earlier software releases are also available in the sub-directory called "Previous_Versions" or in a folder named after the product and version number.
