BETA CAE Systems
announces the release of v16.0.0 of its software suite

ERRATUM issued July 24


About this release

The new ANSA / EPILYSIS / META v16.0.0 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 new 16.0.0 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 new version of the META post-processor, v16.0.0, 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 for crash, durability, CFD and NVH.

The most important new software features and fixes are listed below.

ERRATUM issued July 24

The July 20 installation packages of v16.0.0 were updated. The latest available files are dated July 24.
Please download the updated packages taking into account the following problems that were caused due to differences in the installation directories' structure in the July 20 packages.

1) Running the stand-alone translator ( on Linux platforms was generating the following error message :
".../ansa_v16.0.0/bin/ansa_cad_linux_x86_64: error while loading shared libraries: cannot open shared object file: No such file or directory"
The problem was treated by carrying out a minor correction in the file.
In the updated Linux installer the is properly defined.

2) The translator's GUI file ( ansa_transl_gui64.bat ) was left out of the installer for Windows during compilation.
The problem was treated by adding the ansa_transl_gui64.bat file in the installer (*.msi).
The updated installer for Windows has the ansa_transl_gui64.bat file.

However, there is a known issue remaining, which will be resolved in the following version of the v16.0.x series:
The problem affects the Translators' interface of the distribution for Windows (the Translator GUI that launched by the ansa_transl_gui64.bat).

1) The "Script to run" field on the Translator's interface displays a wrong location path for the ansa_cad64.bat file.
The "Script to run" field reads:
while it should read:
The "Script to run" field is an editable field, so the user can make this correction manually.


New features in ANSA
New features in META
Compatibility and Supported Platforms

New features in ANSA

Multiple Models

Engineers can now work on more than one models within the same ANSA session to visually compare and modify model or solver files, without intervening on the Ids of the incoming models.


Collections of script functions written in BETA scripts or Python (plugin) can be created and handled through the new Plugin Manager and can be automatically loaded when launching ANSA.

Model Browser

The Parts Manager has been replaced by an enhanced tool holding all information associated with every Part/Group. Now, actions previously performed by different tools to gain information or act on specific parts of the model, can be conducted within one unified tool (e.g. view/apply connections referenced by specific parts).


A new Interface has been developed to aid multiple flange pairs handling, significantly reducing process time. Through a new tool flanges can now automatically be identified.


It is now possible to copy a mesh to identical geometrical entities.

Skinned parts can be fused directionally to obtain the watertight model.

The creation of Fillets / Chamfers or conversion to sharp edge is now possible for elements not attached to any geometry (FE).

Volume mesh

A new algorithm has been introduced for the generation of hexahedral elements for cavities dropping the total number of elements as tetra elements are considerably reduced.

Mesh on extracted middle surface

New options have been introduced for selecting and assigning thickness on multiple areas with advanced capabilities.

A new tool named Thick Zones interprets more accurately the material concentration at rib body junctions and creates property zones to control the thickness at these areas.

SETs handling

Boolean operations can now be applied on SETs.

Laminate tool

The Draping tool has been significantly enhanced. The results are now visualized as fiber orientations for improved visibility, the failed areas (elements) are highlighted, and holes & beads can be effectively handled.

Solid Laminates

Solid Laminates are now supported for the LS-DYNA, PAM-CRASH, RADIOSS and PERMAS solver decks.


A new tool is introduced for the Passenger Seat Adjustment. A wizard like functionality is used to select the Protocol for the Front and Side Impact analysis in order to position the Seat according to the desired regulations.

The new LoadcaseManager script offers a bulk LS-DYNA model set up and output of Dummy - Seat system, positioned, depepentrated and restrained for all saved positions.

Squeak and Rattle

The ElineMethod plugin produces the model set up for Squeak and Rattle analysis.


Support of the sub-modeling tool for ANSYS and Abaqus solvers keywords CBDOF and *BOUNDARY, SUBMODEL / *SUBMODEL, TYPE=NODE. ANSYS and Abaqus users can now be benefited from the ANSA capabilities such as the definition of submodels with the aid of Model Cut, and the refinement of submodels using Reconstruct and other meshing functionalities.


Multiple control definition cards are now supported and can be input/output to be used in different Include files.

Kinetics tool

Contacts: The Smooth Method is now supported for simulations running with the HHT dynamic solver.

Design exploration has been introduced for running parametric simulations, to examine how specific design variables affect the behavior of a multibody model.


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