Beta CAE

ANSA is an advanced multidisciplinary CAE pre-processing tool that provides all the necessary functionality for full-model build up, from CAD data to ready-to-run solver input file, in a single integrated environment.
ANSA is the users' preference due to its wide range of features and tools that meet their needs. The list of productive and versatile features is long and the alternative tasks and processes to be completed using them are countless.

All software features are accommodated in an integrated environmet, with highly customizable GUI. The software is available for all contemporary popular operating systems.

CAD data input & clean up
CAD geometry can be read in from neutral file formats, manipulated and healed by the proprietary powerful built-in geometry engine. Additionally, CAD definitions and model structure data in CATIA V4, CATIA V5, NX, Pro/ENGINEERand JT formats can be converted into ANSA files using the available translators. (more...)
Custom interfaces to PDM or SDM systems, powered by scripting, bring product & model structure data into the heart of the software.
A wide range of geometry healing functions, including those for the generation of neutral fibers, deliver geometry descripitons ready to be meshed.

ANSA data management
ANSA DM assures the effective and efficient data handling throughout projects, by streamlining updated model data to engineering teams, allowing the easy sharing of common data and offering access to library items for the analysis dependant solution settings.

Task manager
Integrated workflow manager. A tool where all individual tasks of the development of a vehicle simulation model are included. Tasks in Task Manager are built up from the CAE expert who sets the boundaries between distinct modeling actions and predetermines all modeling parameters that must be respected, leaving to the inexperienced user a minimum degree of interference and limited or none decision making.

Following the versatile mesh area idealization, geometry can be meshed according to modeling requirements by its cutting edge, fully integrated surface and volume meshing algorithms. The numerous proprietary shell meshing algorithms, the high performance and quality volume meshing algorithms, the versatile boundary-layers elements deployment, the Hexa-Interior meshing algorithm, the Acoustic Cavity mesher and the straight forward Wrapping tool, compose a unique mesh generation environment. Furthermore, the integrated batch meshing tool leads to controllable and effortless optimal results, for both shell and volume meshing.


Powered with fully comprehensive parts and welding management tools, ANSA accommodates parts assembly, with alternative node-dependent or independent connections types, appropriate to various disciplines. Interfaces to numerous connections data file-formats allow the completion of a single stage assembly. New concepts introduced, including model hierarchy input, multiple part instances handling, alternative part representations management, model assembly and build up using Generic Entities such as Connectors, Boundary Conditions and Output Requests.

Pre-processing decks
Pre-processing completion is achieved through the uniquely interoperable pre-processing decks for NASTRAN, LS-DYNA, PAM-CRASH, RADIOSS, Abaqus/Standard, Abaqus/Explicit and ANSYS Structural, allowing direct model modification between solvers, including material synchronization. Numerous unique utilities facilitate laborious tasks such as the management of Includes Files, model sub-structuring, entity numbering control etc. ANSA is multidisciplinary by design, in order to simultaneously handle models for Crash, Durability, NVH analysis etc., supporting all entities required by the latest versions of solvers. A Compilation of CFD oriented features are accommodated into special CFD pre-processing decks that support the most popular codes, such as STAR-CD & CCm+, Fluent, OpenFoam etc.

Models reusability
Legacy FE Models can also be read in various formats and optionally refined or coarsened by the automated mesh reconstruction functionality, with a multitude of capabilities. The FE models can even be modified further with a wide range of preprocessing decks functions and tools.

Crash & safety features
Crash and safety modeling is assisted by user friendly features for impactors positioning, seatbelt fastening, positioning and articulation of crash test dummies and "headform" models for passenger and pedestrian safety simulation standard scenarios. The fast and easy kinematics tool solves sophisticated positioning problems, for seats and other mechanisms.

The Laminate Tool is one more enhanced function that assists the modeling of complex parts made of composite materials.

Model integrity checks
Replicating the integrity and correctness checks performed by the solvers, ANSA reports potential modeling flaws and proceeds to model auto-correction actions.

Solution control
The above, along with the user-friendly solution case scenario definition leads to the output of a ready to solve model. Apart from the formats of the solvers for which complete preprocessing decks exist, i.e. NASTRAN, LS-DYNA, PAM-CRASH, RADIOSS, Abaqus/Standard, Abaqus/Explicit and ANSYS, numerous other file formats are supported, for structural, CFD and other solvers.

The core preprocessing functionality of ANSA is enhanced with a substantial number of other advanced tools that allow the user to complete specialized tasks without leaving the software environment. Such tools are the Cross Section Analysis Tool, the BiW Bath Traps Tool and the Fuel Tank Analysis Tool.

One of the most advanced tools developed to meet the needs for fast model modifications is the Morphing Tool. It expands the re-usability of existing models by allowing the versatile procession of alternative variations. Morphing operations are performed on FE or geometry models. Applications include fields like optimization processes and sensitivity analysis.

Scripting automation
The ANSA scripting language is an enhanced programming tool that boosts productivity providing the power to access data and perform custom operations in an automated way. The integrated ANSA environment, powered by the process automation of the scripting language, is a unique modeling solution.

Numerous software features, including the Morphing Tool, the scripting and the process automation, can be combined to offer versatile coupling with optimization codes.
