    BETA CAE Systems Releases ANSA, EPILYSIS, META Suite and KOMVOS v20.1.5

    LUCERNE, Switzerland, Feb 5, 2021 – BETA CAE Systems announces the v20.1.5 release for ANSA/EPILYSIS/ META and KOMVOS, hosting numerous fixes in recently detected issues.




    Follows a selection of the most important items:

    Known issues resolved in ANSA

    CAD Import/Export

    Several cases, related to reading CAD formats, have been successfully combatted, as follows:

    1. Upon reading Neutral files using CoreTechnologie libraries, PID from Layers would not be correctly generated.
    2. Referencing CATIA Translators, 3D Point entities would be erroneously disregarded, when “Read features” mode was activated.
    3. When using ANSA Translator, the import of STEP files was susceptible to missing unit changes, encountered in assemblies designed in mixed units.


    Time required for the creation of the Compare Report and the size of the generated METADBs are now significantly reduced.

    Indicatively, in small models of ∼40 parts, the execution time has been reduced from ∼12min to ∼3min and the generated METADBs size from ∼400MB to ∼9MB. In large models of ∼400 parts, the reduction is even more impressive in the generated METADBs size, from an excess of 15GB to less than 100MB, executed in ∼47min in total.

    FE Representations

    The realization of SPIDER2 Representation could fail in case of nearby attached solids, whereas the treatment of non-circular BOLT holes would not be successfully applied.

    Volume Mesh

    Unexpected termination could occur when the function Structured Mesh > Extrude [Revolute] produced more than one volumes, according to connectivity, PID, or part of the source area.

    Checking Mesh [Void Areas], areas at locations of hanging edge between a warped quad shell/facet and the two corresponding tria shells/facets are not identified as Void Areas anymore.

    Deck Tools

    Unexpected termination could occur upon Units Conversion in a database containing 3D Points.


    Differences between CNCAP and KNCAP with EuroNCAP are now taken into account for Car Marking in the Pedestrian tool.


    The robustness of Direct Morphing DFM functionality has been fortified, in cases of geometry with poor underlying surface quality.

    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 could occur when GPSTRESS was requested on fluid elements upon Output, and when a DRESP2 would reference a DRESP2 with higher ID in SOL200.

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

    Known issues resolved in META

    Decks – Fluent

    Reading times of Fluent .dat result files have been significantly improved and META can now read multiple states of .h5 format for transient analysis. Furthermore, META is no longer terminating while reading “Volume Fraction” scalar results of Fluent .cdat files.

    Decks – TAITherm

    META would unexpectedly terminate, upon auto-detection of TAITherm files.

    NVH Calculators – FRF Assembly

    In certain cases where Linear Combination nodes were used as responses, calculations could be incorrect since v20.1.0, depending on the included loadcases.

    Project Files & METADB

    After loading a Project File, META displayed the list of all available results, besides the ones saved. In addition, Set IDs were not successfully saved in Project Files.

    File Export

    Unexpected termination could occur when exporting in 3DXML format.

    User Toolbars

    In the Crash & Safety domain, Occupant Injury Criteria Toolbar now efficiently offers C-NCAP 2021 Rating, whereas Haigh Diagram was not successfully created for user created states, under the respective Haigh Diagram Toolbar.

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

    Known issues resolved in KOMVOS

    Input Model Definition

    Input Model Definition would not work for CATProduct files, ProE files or JT format trees.

    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 20.1.5 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”.

    1. *Support for Mac OS has been discontinued.
    2. *Support for 32-bit platform has been discontinued for all operating systems.
