LUCERNE, Switzerland, Oct 20, 2026 – BETA CAE Systems is pleased to announce the release of the bug-fix version 25.1.6, for ANSA, EPILYSIS, META and KOMVOS with critical bug fixes and selected implementations.
Follows an overview of the most important items:
Known issues resolved in ANSA
GUI
Unexpected termination would occur when using the ‘[STRIKEOUT:>’ syntax to get the id of a material used in a material reference field in a PART_COMPOSITE property list (i.e. MID1]>MID).
Focusing on visibility, the “Near” function could return inconsistent results when searching around CURVE entities, causing nearby geometry faces or shell mesh that were within the specified search radius to remain hidden.
Model Browser
Abrupt software abortion would take place when editing entity color from Database Browser lists.
Middle Meshing
Middle faces would occasionally not be created in areas with variable thickness.
Connections & Assembly
After executing “Erase FE” of a SPIDER2 connection realized on the “Top Area” of a stamp feature, the elements filling the hole would be added to the “Rest Area” of the stamp feature, causing a subsequent Realize action to fail.
NX Nastran
Empty continuation line upon output would lead to Fatal Error when running NX Nastran.
Abaqus
Under Clearance Tabular Data, Calculation of Bolt Axis provided by Set, was not performed properly.
LS-DYNA
During creation of “DEFORMABLE_TO_RIGID: Rigid: PART”, it was not possible to select a part.
Box Morphing
Boxes with loaded Steady Section Morphing Constraints, would fail to perform morphing correctly.
Optistruct
During output, ANSA would falsely write blank stiffness (K) values in the produced *.fem file for PBUSH properties, leading to errors during FE Analysis.
Known issues resolved in META
Abaqus
Assembly set loading would be incorrect for *.odb files containing instances.
LS-DYNA
Results on transformed Includes were not displayed correctly on the corresponding transformed geometry.
Read Results
When loading a curve from a column ASCII format file using the “Bar Plot from Column” or “Bar Plot from Row” format options, the corresponding command recorded in the session was not automatically recognized as a valid filename.
Focusing on 2D plots, when plotting results from a *.res file, the values of the modal coordinates Q of the flexible body could be displayed significantly higher than expected.
Managing Curve Data
META would terminate unexpectedly in cases of binout files with rbdout section.
Report
Focusing on Spreadsheet Editor, extending LOG10 function to several cells led to corruption of the function. The same corrupted behavior was noticed while loading XLSX spreadsheet with extended LOG10 formulas.
Known issues resolved in KOMVOS
Configuration – GUI
SPDRM action applied in ANSA would not be available in the context menu of parts, although it was configured properly in the dm_profiles.xml.
