    BETA CAE Systems Releases ANSA, EPILYSIS, META Suite and KOMVOS v21.1.3

    LUCERNE, Switzerland, Jun 8, 2021 – BETA CAE Systems announces the availability of v21.1.3 of its software suite, the new second point release of ANSA/EPILYSIS/META and KOMVOS, incorporating numerous fixes in recently detected issues. Increase the reliability of your simulation work with this latest software release.




    The most notable improvements include:

    License Management for ANSA and META

    Focusing on the Command Line arguments, the LM retry option (-lm retry timeout) can now be restricted by user-defined timeout.
    The respective flag is followed by the desired timeout in seconds and its minimum acceptable value is 60.

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

    Known issues resolved in ANSA


    ANSA might abort launching when executed via VirtualGL on remote environments.


    ANSA would cease to respond, when loading specific types of .xml files.
    Indicatively, such .xml files would contain GUI Settings saved with any list windows (e.g. Properties, Materials) visible, affecting ANSA response even upon initial launch.

    Database Browser

    Unexpected termination could occur upon deletion of solid elements when deleted directly (e.g. through the Database Browser list of solids) or indirectly (e.g. through the deletion of other containers like includes or Model Containers).

    Shell Mesh

    Unexpected termination could occur when projecting points to open holes via Project [Holes].

    Pasting nodes that lie on boundary of volumes in light volume representation mode via Grids > Paste [Auto] function would lead to erased volumes.


    Laminate Convert would occasionally lead to unexpected termination.

    Optimization Tool

    Unexpected termination could occur when Cross Sections were morphed and recalculated during a DOE run, or when Simulate was used and the Design Variables modified cross section thickness and shape.

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

    Known issues resolved in EPILYSIS


    DMIG coupling generation weighing factors would not be correct when the coupled Fluid and Structure surfaces were parallel.


    Topometry optimization would stop in first cycle, when a PCOMP property was used.

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

    Known issues resolved in META


    Certain settings in “Fraction Plot Options” of FRF Assembly might not be initialized correctly after Ctrl+N.

    Certain settings in Modal / FRF Correlation Tool would not reset to their default values with Ctrl+N.

    “Output in Unv58” settings under Modal Response would not be restored correctly.

    Read Results

    PAM-CRASH MTOJNT elements, as well as PERMAS EKINMASS scalar results, were not read correctly. Marc Element Type 84 was not read at all, whereas unexpected termination could occur when reading Marc Logarithmic Stress results.


    When multiple META sessions were using femzip NASTRAN models to read results simultaneously, META could become unresponsive. In addition, unexpected termination could occur when coordinates systems were defined with mixed single and double precision.

    States & Animation

    Unexpected termination would occur when Time was shown on the Animation Bar and the selected States Method was Interpolate.

    Identification of Entities & Data

    Parts identify function failed to exclusively identify the picked part in the GL area and, consequently, indicate it in the list.

    Math Operations on Field Data

    Unexpected termination could occur when reading scalar nodal results in Fourier Transformation for Abaqus.

    NVH Calculators

    FRF Assembly: When modal participations were requested for a single component, with no connections, the calculated results would be zero.

    Modal Response: If the method without large masses was used to calculate enforced motion for ASCII modal models, the enforced motion displacement at the excitation points was calculated as zero.

    Project Files & METADB

    Unexpected termination could occur when reading element thickness.

    File Export

    Unexpected termination could occur while exporting a video with animating cycles.

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

    Known issues resolved in KOMVOS


    Thanks to the “Compare Containers” option, available under the Context Menu when selecting Parts, the properties and attributes of multiple Parts can be successfully compared.

    DM Schema Editor

    Clicking OK in the “Accepted Values Editor” window would lead to unexpected termination.

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

    New Documentation in ANSA


    Modular Model and Run Management

    1. Modular set-up of a static simulation for EPILYSIS
    2. Modular set-up of a crash simulation for LS-DYNA

    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 21.1.3 are compatible and can be opened by META version 16.0.0 or later. To be readable by META versions earlier than v16.0.0, they have to be saved selecting the option “Version 16.0.0” or “Version <16.0.0”.

    *Support for Mac OS has been discontinued.

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