About this release

BETA CAE Systems announces the release of v21.1.7.

This last version of the ANSA/EPILYSIS/META and KOMVOS v21.1.x series, hosts numerous fixes in recently detected issues, a highlighted selection of which is featured below:

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


Common issues resolved

Communication with License Manager

A new option to "Save & Retry" for license has been added in the CONFIRMATION dialogue window that pops up in ANSA and META, when the communication with the license server is interrupted. In this way, the user will be able to first save the file and then retry re-acquire license.


ANSA and META could potentially fail to launch on a unique display, while executing batch jobs in parallel via VirtualX.


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


Known issues resolved in ANSA

Connections & Assembly

The calculation of skipped adhesive elements (Cut-off Adhesives) for spotweld and adhesive line realization would produce erroneous results.


Unexpected termination of the Seatbelt Tool would occur, when changing the Number of Shells during Seatbelt re-creation.


The Node Ids would be erroneously renumbered and duplicated, when using the function base.AddToModelContainer(), because of the numbering rules applied on the Model Browser container of the Nodes.


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


Known issues resolved in EPILYSIS


Unexpected termination would occur in optimization with frequency response, coupled with enforced motion.

In SOL200 runs, the CDAMP1/CDAMP3 elements would not be connected correctly with PDAMP properties. In addition, values from DVPREL entries would not be not passed.

Known issues resolved in META

BETA Packager Installer

The Toolbars Packager can now handle function calls that use the "dotted" notation. The dots will be automatically replaced by double underscores, so that the respective functions are created without any issues.


Unexpected termination could occur while reading curves from .h5 files, due to memory leak.


Results could not be loaded correctly while reading .erfh5 files.

Managing Curve Data

When reading Contribution analysis results without Total Curve, the corresponding plots were not populated correctly.

LS-DYNA: Curves would not be properly plotted from a binout file, when the same Id was available for different entity types of 'swforc'.

Total Panel contributions would not be not read correctly for NX-Nastran.

Subcases States were missing when reading Nastran .h5 SOL111 results with Stresses.

NVH Calculators & Modal Response

FS Coupling: Too many structural elements would be included in the FSI, when the fluid mesh penetrated the surrounding structure in a way that the free surface rested significantly outside the surrounding panels.

When two FLUID PIDs had common faces, the FSI calculation would occasionally take into account faces which were not part of the outer surface of the fluid.

Fixed inaccurate numerical transient response analysis results, in cases where rigid body modes contributed to the response.


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 21.1.7 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 platforms has been discontinued for all operating systems.
