    LUCERNE, Switzerland, Mar 31, 2021 – BETA CAE Systems announces the first bug-fix release for ANSA/EPILYSIS/ META and KOMVOS, version 21.1.1, hosting numerous fixes in recently detected issues.

    Known issues resolved in ANSA

    General

    In case the “Offsets and conflict resolution” policy for a category is set to “Offset”, the resolution of conflicts between defined/undefined and undefined/undefined entities will now be effectively enabled, before offsets are applied. This is achieved thanks to the successful introduction of ANSA.defaults setting “Conflict resolution for offset mode”, affecting the behavior of both File > Merge and File > Input, as well as all DM > Load functions.

    Compare

    ANSA could terminate unexpectedly, when the Compare Tool was executed on 2 models, in 2 windows, via script –in specific, via base.CompareTool() or base.Compare().

    Data Management

    Unexpected termination could occur under Compare Tool > Compare selected items function of DM Browser, when the option “Overwrite current model” was by default activated in the Input/Merge Parameters settings.

    Connections & Assembly

    Unexpected termination might occur when selecting as connectivity of a GEB or Connector a Model Container with hundreds of thousands elements, having the “highlight ” mode enabled.

    Shell Mesh

    Unexpected termination could occur when the Collapse Small Heights function, under Mesh Generation menu, was used in large STL models.

    Volume Mesh

    The generation of tetra Layers is now sped-up by approx. 80 %. On top of that, cases where Layers generation would create hanging edges with the side area have now been fixed.

    Furthermore, under the broader area of Structured Mesh, the Map function now correctly creates solid elements in light volume representation and ANSA will not unexpectedly terminate during Volume Meshing on machines with many threads.

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

    Known issues resolved in EPILYSIS

    Elements

    Differences in Eigenmodes would be produced due to the CQUAD8 bending curvature evaluation, whereas –focusing on SOL103– differences in Eigenmodes would be produced due to the CTRIA6 with deleted edge nodes.

    Contacts

    Wrong displacements would be output for constrained nodes with enforced displacements for intermediate load steps with NLPARM >INTOUT = ALL/YES.

    Output Results

    If elements of a fluid solid mesh consist of grids with the same coordinates, a fatal error would wrongly be issued and the elements would be listed in the .f06 file.

    SPCFORCES and MPCFORCES resultants would be incorrect in case of a grid with CD.

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

    Known issues resolved in META

    General

    Several Settings issues have been resolved, including:

    Certain unit systems in FRF Assembly and in Modal/FRF Correlation were not stored in META.defaults correctly.

    Unit settings from “Results” card and “Global Unit System ” were not saved in META.defaults at all.

    Modal Response unit systems and “Nodal Local System” setting, as well as CORD2R settings in “Modal Model Builder”, would not be updated correctly from META.defaults.

    Settings in Read results tab would reset to values different from the ones saved in META.defaults file via Ctrl+N.

    In a similar manner, the “Ignore Failed Elements” option would not reset to the default value when Ctrl+N was pressed with the “Reset Settings” option enabled.

    Collaboration Tool

    META would not allow full include sharing of Pam-Crash models, while in Collaboration.

    Graphics

    Hardware acceleration is now functional, when launching ANSA/META via XRDP.

    Read Results

    Template Manager would terminate unexpectedly, while loading Nodal Point Stress results from an ADAMS .res file.

    Math Operations on Field Data

    Unexpected termination occurred when performing Linear combination > Fourier transformation on 3D results after Ctrl+N.

    Report

    Focusing on Statistics, upon the creation of a report in PDF format, the .metadb would fail to be included as 3D model.

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

    Known issues resolved in KOMVOS

    Data Management

    Under Product Tree Editor > Input model definition, users can now distinguish whether to keep the current ANSA units or the units of the input file, thanks to the new ” Units ” setting. As a consequence, the ANSA units and transformation matrices will be converted accordingly.

    Machine Learning

    The speed of the feature extraction process for feature-based Machine Learning training has been accelerated. Specifically, time requirements have been reduced by 5-10″’, depending on the size of the models.

    In addition, it is now possible to successfully see and save predicted results as KeyValue Reports in My Experiments list of the DV Based Prediction window.

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