Enhancements in ANSA


The IMPDISP Keyword is updated according to RADIOSS versions 11.0 and onwards.

Known issues resolved in ANSA


Sorting by column would not be available in the Check List.

Script>Load: Upon activation, the File Manager would start in the user's home directory, instead of the current working directory.

CAD Translators

Translator would not operate as expected due to an issue with the command line syntax, related to "-idir" argument.

Connections & Assembly

By Connections>Check double connections, the selection of check method -i.e. "By absolute distance" or "By average thickness" would be regarded conversely, leading to erroneous results.

GEBs referring to other GEBs in their connectivity field, would not be applied.


When using the function Compare With Current Model the temporary models created during executing the Compare Tool, remained loaded after the completion of the comparison process.

Shell Mesh

By Grids Release, selected frozen elements were also affected.

In certain cases, when using Thick Zones not all of the defined zones would be created around a triple bound.

Volume Mesh

Check of Negative Volumes reported erroneous number of violating elements.


Checks: Upon fixing free nodes, all BCs defined on SETs would be erased.

Laminates: Comments for woven laminate layers were erroneously written, resulting in unexpected termination during file input.

Upon running a sequence of checks through a script, unexpected termination could occur.


During input, the keyword following the MATT8 definition was not read properly.

NVH – Console

Grid Point cards would not open when Sockets were selected with double-click, within the NVH Console diagram.


Cases where the keyword *DEFINE_CURVE_FUNCTION was erroneously output multiple times, when the option "Disregard includes" was inactive.

Float values, in the field NP of the *AIRBAG_PARTICLE element card, could lead to unexpected termination.


When mapping NASTRAN pressures to Pam-Crash, mapped pressure and re-orientation of target mesh were erroneously indicated.


Applying Direct Morphing with DFM could generate distorted geometry.


The issues with the Script PartToPID have been resolved.
