Enhancements and known issues resolved in ANSA

Enhancements in ANSA

Model Browser

Replace > Part/Subsystem: The mapping of solid properties is now supported while the mapping of solid elements has been further improved.


New offset options have been introduced for the correct marking of the seat impact area for ECER17.

CAD to ANSA Translators

NX12 files are now supported using the NXOpen libraries.

Known issues resolved in ANSA


Utilities >Transform: This function could occasionally lead to corrupted database, when applied on a model that contained volumes.

Model Browser

Connections: After Converting FE to Connections, the contact used by the connection would not appear in the Model Browser as related to the connected Parts.

File > Input, Merge: All connections read would be offset by the maximum current connection ID. This could lead to connections quickly getting huge IDs. Subsequently, once the max ID reached the 2^31 limit, no additional connections could be created.

FE Representations > NASTRAN CWELD: Duplicate CWELDs could be created upon the realization of such connections when the specified spacing was smaller than the existing element length.

Volume Mesh

Scripting > mesh.VolumesMeshV():

- Invalid argument would lead to unexpected termination.

- Execution in nogui mode could lead to unexpected termination.

Batch Meshing

General: When both connected multi-instantiated parts and frozen mesh existed, "Synchronize representation" or "Batch Mesh" could lead to unexpected termination.


Output: ANSA would occasionally cease to respond during File > Output of ∗.gz files in case of insufficient disk space.


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


Support of ∗CONSTRAINED_SPR2 elements results (Failure, Length, Resultant Moment) when loading from swforc and binout LS- DYNA files.

NVH Calculators

When requesting animations from the FRF Assembly tool, the rigid body components were animated with zero displacements. They are now calculated based on their geometrical characteristics.

Modal Parameter Estimation

A button has been added to collect all poles of last order without having to explicitly pick them with the mouse.

Known issues resolved in META


The shortcut "Ctrl + Left/Right Arrows" to switch visibility, could be applied in wrong states.


Curves from LS-DYNA elout files with solid strain results might not be read correctly.

Performance improvement in Copying - Pasting curves.

Curve Functions

Type Min was incorrectly calculated in case the "Apply on X-range" did not match a curve point.

Project Files

Saving project with states created by User Field Function failed to save all states.


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 18.1.2 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".

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