Enhancements and known issues resolved in ANSA

Enhancements in ANSA

CAD to ANSA Translators

The new library of CoreTechnologie (CT 2020 SP1 HF) is now available, supporting the formats of NX1899 (UGOpen) and Inventor 2020.

Known issues resolved in ANSA

CAD Import/Export

Hierarchies might not be loaded and Geometric Sets could be lost, when the setting "Translators [CATIA> Force single part] " was active, e.g. in CAD to ANSA functionality.

Moreover, focusing on CATIA Translators, activation of the "Read Features" option could result in a translation failure. ANSA versions affected depended on the operating system; Windows being more susceptible.

Batch Meshing

Abnormal termination could occur in cases where Batch Mesh was set up in units of meters [m].


NASTRAN Header would not be correctly read, in case it contained an empty SET.


MEDINA MPC_LSURFACE definitions, imported from ANSA versions 20.0.0 and older, would not be correctly exported into Medina .bif file, even if listed in DB Browser.

Furthermore, MPC_LSURFACE definitions, imported from ANSA versions 20.0.0 and older, would not be correctly exported into PERMAS .dat file, even if they were listed in DB Browser. The export takes place as expected since ANSA v20.0.4.


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


Enhancements and known issues resolved in META

Enhancements in META

Project Files & METADB

When loading a .metadb file per drag 'n' drop and a geometry file is already read in META, a menu pops up for the handling of the .metadb file. The available further actions to be taken are: Load, Overlay and Cancel.

User Toolbars – Fatigue > Haigh Diagram

The calculation time of the Safety Factor has been significantly reduced. This is an implementation that goes along with the enhanced responsiveness of 2D Plot window by displaying only up to 1000 points on the diagram.

Known issues resolved in META


Unexpected termination could occur upon reading a new model, if Render functionality was enabled in multiple windows.

Read Results

Results were not properly loaded, even if any geometry parts were previously deleted from the model.

In addition, reading of results from column ASCII files was distorted in versions 20.0.4 and 20.1.2, whereas differences in HDF format written by NASTRAN v2020 compared to v2020 ALPHA caused an unexpected termination when trying to read the file.


Unexpected termination could occur while reading results from more than one lossy .metadb file.

NVH Calculators – Modal Parameter Estimation

Since v20.0.0, curves were not created when the option to plot curves was selected, without the option to output to .unv file at the end of the analysis. The problem occurred only when executing the function via GUI, whereas the process was applied correctly when using the respective command.

Data Management

META would cease to respond, when trying to save a curve with an asterisk (*) in its name to DM.

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 20.0.5 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".

Support for Mac OS has been discontinued.

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