Enhancements and known issues resolved in ANSA

Enhancements in ANSA


Undo/Redo is also available while selecting or deselecting model entities, either from working area or from lists.

Model entities chosen for Show Only can now be automatically fit to screen.

CAD to ANSA Translators

The translation capabilities for reading neutral CAD files have been expanded with the option to select the CT library.


The existing functionality of ANSA connections creation has been enriched with the conversion of NASTRAN CWELDS elements to seamlines.

The capabilities of ANSA connections’ handling have been expanded in RBE3-CELAS1-RBE3 & RBE3-CBUSH-RBE3 representations, which can now generate zero-body elements as well.


Shell Mesh: The Grids[Align] function provides now the direct alignment on complex curved lines, when selecting more than 3 points.

Volume Mesh: The additional supported parameters of the script function AdvancedLayersParameters provide an efficient control of the layers generation.

Batch Meshing: CFD mesh generation with proximity areas is now further accelerated.


Laminate Tool: Draping results can be accomplished with the Sliding algorithm as well.


The Penetration>Intersections fix has been improved with the option to control the movement of nodes by freezing specific areas.

Processing time has been significantly reduced by using multiple cores for checking contacts and penetrations (property thickness, user thickness, distance range).


THERMAL: A new wizard-based assistant automates the Thermal analysis model set up.


The substructuring analysis has been introduced for LS-DYNA.


Multiple Control Cards can be handled in the same model.


A new function has been added to quickly modify the tubes’ diameter through the enhanced Direct Morphing functionality.

Known issues resolved in ANSA


Scripting: Extraction of middle skin surfaces using the function Base.Skin() would stop when an already skinned part was found.

Volume Mesh

Cavity: In certain cases the Hexa Dominant generator would fail to project on the seats.


AIRBAG: The field NP of the *AIRBAG_PARTICLE would accept float values.


The selection of the second node set during the creation of line elements or MPCs would occasionally be unavailable after the first use.

NVH Console

The performance of the Load Case Manager would occasionally be poor, when handling big models.


DLOADs applied on continuum shells would not be drawn.

Enhancements and known issues resolved in META

Enhancements in META

Supported Interfaces

Support of the initial Ids of hierarchically structured geometries (Abaqus, PAM-CRASH and RADIOSS sub-structured by parts, modules and id pools respectively)

Abaqus v2016.

ADINA 10.2 Contact results from OP2 files.

ANSYS COMBIN elements.

Support of the NLOC option of LS-DYNA *PART_COMPOSITE

Support of intermediate Stress results (NLOPRM OUTCTRL = INTERM) from NASTRAN OP2 files.

NASTRAN 2016 results of Normal Velocity (NVELOCITY) and Vibration Intensity (VINTENSITY)

PAM-CRASH Implicit second order elements.

Support of the reading of Stiffness, Damping & Mass sensitivities as Curve results from NASTRAN OP2 files.

Von Mises Bending and Von Mises Membrane results from PAM-CRASH ERF files.

Support of RadTherm Thermal Links as SETs.

Support of streamlines for Ensight adaptive mesh.

Results Loading

New options have been added for loading Displacements / Velocities / Accelerations results on Cylindrical / Spherical local coordinate systems.

Drawing Styles

Increased drawing performance when Entities mode is selected for model coloring.

New Pcomp Zones drawing style


Part properties are now read and displayed when identifying a part.

Significant performance improvement of the Advanced Filter execution on big models.

NVH Calculators

The performance of FRF Assembly tool has been improved.

Video post processing

Improvements and new features for tracking results on videos such as, the capability to copy track points between videos in different windows, new options for plotting tracked results as curves, and context menu added on tracked points.

File Output

Improved performance for saving compressed project files (both Lossy and Lossless).


Improvements and new features in CompositePost toolbar including the report generation for selected parts in Laminate Tool, the display of Material/Fiber orientation as continuous lines, and the support of ANSA LAMINATES.

Wing Deflection post processing

A new toolbar, the WingDeflectionPost, to create Warping, Profile position, Profile position, Section deformation, and Force plots based on the deformation of the wing.

Known issues resolved in META

Supported Interfaces

Abaqus *DISTRIBUTION for defining thickness was not supported correctly.

Results Loading

Files located in folders with very long names could not be accessed on MS-Windows.

MS-Windows filepaths with slashes and backslashes were considered to be different.

Units Conversion

Wrong factor would be used for Units conversions from/to tons.

Curve Functions

BrIC calculation was not correct when curves were not in SI unit system.

NVH Calculators

Responses calculated from FRF Assembly for multiple frequency ranges might not be correct.


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 16.2.0 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.

Customers who are served by a local business agent should contact the local support channel channel for software distribution details.

What to download

All files required for the installation of this version reside in the folder named "BETA_CAE_Systems_v16.2.0" and are dated as of April 28, 2016. These files should replace any pre-releases or other files downloaded prior to that date.
The distribution of this version of our pre- and post-processing suite is packaged in one, single, unified installation file, that invokes the respective installer and guides the procedure for the installation of the required components.

For the installation of the software on each platform type, installer file residing in the folder with respective platform name, for Linux and MacOS or the respective .msi installer file for Windows, 64bit, have to be downloaded.

In addition to the above, optionally, the µETA Viewer is available to be downloaded for each supported platform.

The tutorials and the example files reside in the folder named "TUTORIALS". This folder includes the complete package of the tutorials and example files, and a package with only the updated ones.

The Abaqus libraries required for the post-processing of Abaqus .odb files are included in the installation package and can be optionally unpacked.

Earlier software releases are also available in the sub-directory called "old" or in a folder named after the product and version number.
