I. Overview of Software
The advanced CAE pre-processing software for complete model build up
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.
II. Overview Software functions
All software features are accommodated in an integrated environment, with highly customisable GUI. The software is available for all contemporary popular operating systems in 32bit and 64bit architecture with multi-core CPU usage. The accelerated graphics, the rapid confirmations and function access, the GUI customisation options, the model browser and lists handling, the filtering and modification operations, and the integrated search engine comprise a user friendly environment that ensures outstanding performance and productivity.
2. CAD data input & clean up
CAD definitions and model structure data in CATIA V4, CATIA V5, NX, Pro/ENGINEER and JT formats can be converted into ANSA files using the available translators. Moreover, custom interfaces to PDM or SDM systems, powered by scripting, bring product and model structure data into the heart of the software.
3. ANSA data management
ANSA Data Management (ANSA DM) is a centralized data management system, used to collect and store in a structured and hierarchical form all engineering data that are used during the development process of a vehicle simulation model. It 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 dependent solution settings. The DM Browser, moreover, allows the browsing of the DM Root to identify the available CAD versions, study versions and representations for comparison and model update.
4. Model Comparison and update
An integrated tool that compares two models in order to identify differences in geometry, attributes, solver-specific definitions, as well as connections. User friendly navigation and identification features are provided while a complete or partial replacement can be performed, updating the model according to user directions.
5. Process Automation
Task Manager and scripting language provide a unique modeling solution for automated and effective applications.
The integrated Batch Meshing tool leads to controllable and effortless optimal results, for both shell and volume meshing. Following the versatile mesh area idealization, geometry can be meshed according to modeling requirements by cutting edge surface and volume meshing and wrapping algorithms.
Powered with fully comprehensive parts and welding management tools, 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, parts comparison-replacement and update as well as special joining type creation.
8. Includes configuratior
Different model variants or load cases can be compiled with available include files through one of ANSA’s special tools. This enables the creation of particular model configuration even without loading the respective data.
9. Pre-processing decks
Pre-processing completion is achieved through the uniquely interoperable pre-processing decks for NASTRAN, LS-DYNA, PAMCRASH, RADIOSS, Abaqus/Standard, Abaqus/Explicit, PERMAS 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.
10. Analysis tools
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.
11. Model integrity checks
Replicates the integrity and correctness checks performed by the solvers, reports potential modeling flaws and proceeds to model auto-correction actions.
12. Solution control
The above, along with the user-friendly solution 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, PERMAS, Abaqus/Standard, Abaqus/Explicit and ANSYS, numerous other file formats are supported, for structural, CFD as well as other solvers.
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.
The core preprocessing functionality is enhanced with a substantial number of other advanced tools that allow the user to complete specialized tasks without having to leave the software environment. Those tools are the Cross Section Analysis Tool, the Volume Traps Tool and the Fuel Tank Analysis Tool.
Numerous software features, including the Morphing Tool, the scripting and the process automation, can be combined to offer versatile coupling with optimization codes.
