About this release

BETA CAE Systems S.A. announces the release of the version 16.1.0 of the ANSA / EPILYSIS / META suite with new tools and capabilities to further augment functionality and facilitate CAE processes.

The ANSA / EPILYSIS / META v16x suite, brings BETA CAE Systems software suite to a new dimension, by providing complete solutions in the CAE field. Loyal to our commitment to deliver best-in-class software, we achieve our goal by introducing the new solver Eπilysys, as well as by providing new tools and functions per domain and per discipline.

The 16x version of the ANSA pre- processor provides full compatibility with previous major versions. As with every major release, a broad range of new features and enhancements to existing ones add value to our solutions, reinforce overall process consistency, accelerate user performance, and provide a considerable boost on productivity.

The EPILYSIS solver is the new addition to the BETA CAE Systems analysis tools family and is available with the ANSA / EPILYSIS / META suite. Named after the Greek word for solution, it operates as a solution in the field of Finite Element Analysis embodying the accumulated knowledge from 25 years of collaboration with the CAE community. EPILYSIS covers numerous solution types and intends to bridge the gap between pre- and post- processing for disciplines such as Structural, NVH, Optimization, and more.

The v16x version of the µETA post-processor builds upon the tools available in previous releases, now supporting an increased array of new interfaces including EPILYSIS, the in-house solver of BETA CAE Systems, as well as enhancing the multi-disciplinary tools.

The most important additions and fixes implemented in v16.1.0 are listed below.

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 v16.1.0, v16.2.0, v16.3.0 and so on, with code corrections but also with additional software features and enhancements are released every three months.

- Second point releases, such as v16.0.1, v16.0.2 etc. 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 v16.1.0 brings additional features and code corrections on v16.0.x.

New features in ANSA


CATProduct model definition can now be imported in the in the Product Tree Editor offering better control and facilitating the translation process.

New improvements in the Stand-alone Translator offer a more intuitive interface, and increased capabilities in settings handling.

NX UGOpen: Weld spots properly defined in NX, are now automatically recognized by the translator and converted to spotwelds. The connectivity is also filled-in automatically for each spotweld on parts' Module Ids.

Geometric entities handling

Handling Geometric entities, such as, Faces, CONs and Hot Points can now be automated through scripting.


Shell mesh: A new Wrap [Constant Length] function offers now enhanced capabilities and the advantage of making modifications throughout the entire process.

Volume Mesh: Layers generation at concave areas is now improved to minimize squeezing.

Hexa Block: The steps to create both the box structure and the mesh, can now be stored for later reproduction reducing significantly preparation time.

New and enhanced functionality that significantly improves and facilitates complicated and high demanding meshing requirements for biomechanics applications.

The Jacobian quality criterion can now be effectively handled through the ability to set the desired calculation options.

Connections / Assembly

The capabilities of ANSA connection handling has been expanded in Bolt and Adhesive representations (FE elements) which can now be automatically converted to connection entities.

Solver Interfaces

The visualization of Material Orientation is now improved by continuous lines that define the orientation. This applies also on the Layers of composites.

The Mass Balanced tool has been improved to offer new features and a more user-friendly interface. The new features include an alternative calculation method that takes into account the Inertia values and, the ability to add masses on only the necessary regions.

Matereality: A new tool has been developed, in cooperation with Matereality LLC, that integrates material model data feeds into ANSA.


The coupling of the dummy to the seat has been facilitated through a stepwise assistant enabling quick coupling of their Kinematic Configurations.


New Thermal Analysis solution keywords have been introduced for NASTRAN.


Support of the version 13.0.

Information of Encrypted properties can now be read.


A new special interface for setting-up models for the TAU solver has been introduced.


Bodies: The option to merge two or more bodies into a single one is now provided.

Design Analysis>D.Simulator: More than one Objective can now be selected to issue results for either Design Studies or Design of Experiments.


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