Interoperable Decks:

ANSA’s pioneered and successfully incorporated the concept of interoperable decks between NASTRAN, LS-DYNA, PAM-CRASH, RADIOSS, ABAQUS (Standards/Explicit) and ANSYS Structural. This allows the user for a direct model modification between solvers & even synchronization of material information. This allows for minimum data duplication for individual solvers thus reducing hardware costs. It is also a huge assist while using and reusing legacy models and converting between solver specific input files.

Card Interface & tool tip:

The keyword cards in ANSA are interrelated and inter accessible. This enhances the ability to create and reference entities on the fly. Assistance for NASTRAN, LS – DYNA, ABAQUS (Standards/Explicit), PAM – CRASH, RADIOSS & OPEN – FOAM have been intelligently included in ANSA so as to provide the user with tool tips for all the keyword cards. These tools tips are a direct replica from the user manuals of the respective solvers. This not only increases the productivity of the user with rookie knowledge of the solver decks, but enhances the model accuracy aswell.

GEB (Generic Entity Builders):

The concept of referencing FE entities through geometry equivalents has been further explored and efficiently used in the handling the various other solver specific entities. This has proved to be as major benefit in Mass trimming, output request creations, boundary conditions definition & set creation and maintenance. ANSA’s scripting abilities further enhances its ability to handles them on a massive scale and thus help in data roll-overs from legacy models with outstanding efficiency.

Laminate Tool:

The Laminate Tool is one more enhanced function that assists the modeling of complex parts made of composite materials. A single interface suffices the operation of creation & modification of layers, material orientation and definition of stack orders. This is common between NASTRAN, ABAQUS (Standards/Explicit), LS – DYNA, RADIOSS & ANSYS decks. It encompasses the ability to create laminate properties & layers on the fly, off an existing FE entity or can read a NASTRAN PCOMP layers from legacy models to generate corresponding properties.

Safety Tools:

Based on unique needs of the crash & safety engineering community ANSA has build and integrated special tools to help in creation of occupant safety models with ease. These tools are assisted by user friendly features for impactors positioning, seatbelt fastening, positioning and articulation of crash test dummies and "head form" models for passenger and pedestrian safety simulation standard scenarios.

Model Checks:

Various Models checks have been incorporated in the ANSA’s deck menu to enhance the model integrity & accuracy. These checks are based on individual solvers and thus help in producing valid solver – ready models. The tool is fully integrated so that the user can interact with the model to investigate potential problem regions, validate check results and proceed to auto – fix them based on the situation.

Renumbering tool:

This tool provides a simple and extensive way to renumber a multitude of entities. User can define unique numbering rules based on properties, ANSA parts, include files, type of FE entities or even a combination of all. These rules provide a template which allows users across the organization to quickly reapply the numbering scheme specified in the standard modeling procedure. It also houses a reporting tool for model review.

Cross Section tool:

ANSA has a ‘one – of – a – kind’ Cross-section analysis tool used for both thin & thick sections. This tool allows the user to extract cross-sectional geometric properties from a multiple of cross – sections on a given FE or geometric model. The tool also can be used for stress analysis of cross – sections based on variable loads and loading points which can further be displayed in contours. Further more these cross – sections can be replaced by bar / beam property entities based model which are automatically created and integrated into solver decks. Working in coordination with the morphing capability of ANSA, one can easily create multiple models for cross – section optimization studies. A detailed report generation compliments the tool to manage such information.

Tank tool:

It’s a unique built – in tool which provides solution to fuel tank analysis requirements of various industries. This tool is used to generate numerical analysis results of tank volume vs. fuel, for arbitrary car orientations. It comes in very handy to determine the optimum filling and suction points, and conduct detailed analysis on the filling process. Volume – based, automatic generation of SPH elements to model fuel can be carried out with much ease.

Volume Trap tool:

The V-Trap tool in ANSA is studies regions of resting liquids or even gas bubbles and enclosures. This is useful for such processes as immersion and extraction of Body – In – White (BIW) in Virtual bath analysis for various dipping orientations. It has proven to be accurate in computing for Bubbles and residue liquid ponds. The tool can be fully automated using ANSA’s scripting capabilities.

Mechanism tool:

This is a result of an out of the box approach to solving problems in accurately positioning complex subsystems & components based on the rigid body dynamics. The tools incorporated functions which create rigid body definitions for corresponding FE entities with minimum user interaction. A fully integrated Multi Body Dynamics Solver then utilized the kinematics relations between these rigid bodies to solve for complex positioning and modeling scenarios. These tools bring a great advantage to the user especially involved in modeling seat – dummy positioning, suspension system models, retractable roof systems and other mechanisms.
