ANSA is an advanced CAE pre-processing tool for Finite Element Analysis 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’ favorite, due to its wide range of features and tools that meet their needs. The list of productive and versatile ANSA functions is long, and the alternative tasks and processes to be completed using them are countless.
CAD geometry can be read in from CATIA V4, CATIA V5 and Unigraphics NX2 data files or from neutral files (IGES, STEP, etc.) and manipulated by ANSA’s powerful built-in geometry engine.

Following the versatile mesh area idealization, geometry can be meshed according to modeling requirements by its cutting edge, fully integrated surface and volume meshing functionality. Furthermore, the integrated batch meshing tool leads to controllable and effortless optimal meshing results.
Powered with fully comprehensive parts and welding management tools, ANSA allows versatile parts assembly, with alternative node-dependent or -independent connections types. The advanced exchange of connections data through vip, vip2 and xml files succeeds in the completion of a single stage parts connection.
Pre-processing completion is achieved through the uniquely interoperating pre-processing decks for NASTRAN, DYNA, PAM-CRASH, RADIOSS, ABAQUS and ANSYS, allowing direct model modification between solvers.
ANSA is multidisciplinary by design, in order to simultaneously handle models for Crash, Durability, NVH, CFD analysis etc., supporting all entities required by various solvers.

Legacy FE Models can also be read in various formats and optionally refined or coarsened by the automated mesh reconstruction functionality, which has incredible capabilities. The FE models can even be modified further with a wide range of pre-processing decks functions and tools.
Crash and safety modeling is assisted by user friendly features for the positioning and articulation of crash test dummies and “headform” models for passenger and pedestrian safety simulation standard scenarios.
The Laminate Tool is one more enhanced function that assists the modeling of complex parts made of composite materials.
Replicating the integrity and correctness checks performed by the solvers, ANSA reports potential modeling flaws and proceeds to model auto-correction actions.
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 pre-processing decks exist, i.e. NASTRAN, DYNA, PAM-CRASH, RADIOSS, ABAQUS and ANSYS, numerous other file formats are supported, for structural, CFD and other solvers.
The core pre-processing 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 contemporary needs for fast model modifications is the Morphing Tool. The ANSA Morphing Tool provides new boundaries to existing models by allowing the versatile production of alternative models based on a single master model. The tool may be used simply for evolutionary changes or sensitivity analysis. The powerful ANSA scripting language allows the coupling of the Morphing Tool with any parametric script driven optimizer within a cycle towards optimal modeling.

The ANSA scripting language is an enhanced programming tool that boosts productivity by giving to the user 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.
