Understanding the Software Release Schedule

The plan

We are committed in delivering improved and enhanced software releases, the soonest possible, in order to meet the requirement of our customers for the continuous improvement of their experience and work. Therefore, we are working in releasing new software versions with code corrections, new software features and enhancements, in regular, frequent intervals.

- A major software version is released every year.

- First point releases, such as v15.1.0, v15.2.0, v15.3.0 and so on, with code corrections but also with additional software features and enhancements are released every three months.

- Second point releases, such as v15.2.1, v15.2.2, v15.2.3 mainly with code corrections only upon their parent first point release, are scheduled on a monthly basis.

Each software release is accompanied by a detailed description of the introduced corrections and/or additions so that our customers can decide whether it is critical to implement this release in their environment.

This release

This release of v15.3.0 implements enhancements and code corrections on the v15.2.x branch.

New features and known issues resolved in ANSA

New features in ANSA


Support of new CT libraries for CATIA.

Connections & Assembly

Enhancements made in the Connection Manager interface.

Enhancements made in connections representations.

Shell Mesh

Perimeters start/end points and vectors information make capable the nodal spacing through scripting.


Known issues resolved in ANSA

Connections & Assembly:

The "Step Length" option would not be respected by EDGE-WELD-SHELL.

The nodes of the RBE3 elements were not pasted on pentahedral elements.

Shell Mesh

Fill>Gaps: Performance improvement for cases with big number of identified gaps.

Volume mesh

Layers: Performance improvements in layers generation for cases where side macroareas consisted on multiple faces.

The script function VolumesOffset would not consider the option to start from the middle surface.


M00 file formats would occasionally read incorrectly the tree format and the Module Ids.

Non-visible entities would participate in flanges detection.

Reading Special Numbering rules would not be displayed when the option "Filter by source with expression" was used.


Occasionally the *DAMAGE INITIATION options were not read through the MAT DB.


The Dependency check would wrongly report the NCOG node after conversion of OTMCO to PAM RBODY.


Applying Pre-tension through GEB_BC would occasionally lead to unexpected termination.


The issue with the misleading color of Frozen Control Points has been resolved.

Create>Bead: A missing check for the Radius fields would occasionally prevent optimal mesh.

New features and known issues resolved in META

New features in META

Supported interfaces

Support of ANSYS elements SOLID87 and SOLID90.

Support of THESEUS-FE results RP02 and YPREC.

User Field Functions

Applicable to CFD analyses, new element result "cellheight" assigns to the wall parts, as scalar function, the height of the first cell of the fluid.

Known issues resolved in META

Supported interfaces

Incorrect calculation of centroid values for certain ANSYS TRIA6 elements.

Incorrect reading of the LS-Dyna *ELEMENT_SHELL_THICKNESS_OFFSET keyword.

Incorrect reading of certain ANSA Parts from ANSA comments that contained LAMINATE information.


Stress Linearization results were not calculated for newly added paths.

For RADIOSS T0x files it was not possible to plot graphs of follow nodes if the nodes belonged to different time history ids.

NVH Calculators

In the FRF Assembly tool the transfer functions plot would be empty if the option Sum x,y,z Transfer Paths was enabled.

In the Modal Response tool, when reading loadcases from Nastran files, the local coordinate systems of excitation nodes were not referenced.


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.

The .metadb files saved with META version 15.3.0 are compatible and can be opened by earlier versions of META.

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