 | CATIA V4 Generative Part Stress Analysis (GPS) provides designers early in the product development process a transparent stress analysis tool as a guide for the design of cast or forged parts. Interacting with the part and not a finite element model, designers untrained in analysis can examine the stress on a part using only six simple steps. Working in this way can drastically reduce the time required to do product concept design. Features - Complete analysis system including meshing, solving and post processing
- Requires virtually no finite element analysis skills
- Invoke analysis information anytime in the development process
- Works in a team environment with other analysis program
- Ability to work on part instead of a finite element model
- Solves static problems
- Automatically adapts a mesh to reach a desired level of precision
- Customize library for selecting material by name
- Choose from a range of restraint specifications and load types
- Enables the administrator to modify parameters for computation and model generation
- Generates, computes and displays model results
- Supports batch job submission for asynchronous processing
- Compute and display stress analysis information
- Support of associative skins
- Improved computation time based on sparse solver techniques
- Multi-selection capabilities for restraint and loads
- Dynamic computation with structural and non structural mass
Key customer benefits - Early analysis
Due to the simplicity of the interface and generative capabilities, designers are able to use analysis for design guidance early in the product development process.
- Analysis anytime
GPS works with other CATIA analysis products providing additional capabilities in a seamless manner for in-depth analyses throughout the development process.
- Simple to use
Designers work directly with exact solid models to specify material, restraints and loads using design terminology such as clamped, sliding or contact restraint. Thus, you do not need advanced finite element analysis skills. Further simplifying the designer's task, the object-oriented Motif interface presents you with load and restraint options for the selected entity.
- Highly automated
GPS can evaluate the part and suggest the optimal solving technology. This choice is based on the model size (in degrees of freedom) versus the compute resource available. Adaptive mesh generation permits you to simply specify the desired degree of precision for a region of a design and the system will adapt the mesh to reach that required precision.
- Numerous load and restraint choices
You can restrain a part using any of the following restraint types: - clamped
- sliding
- contact
- cylindrical
- conical
- revolute
- restraint by a virtual part
You can select from the following for specifying loads: - Pressure
- Traction
- Contact
- Force
- Momentum
- Volume body force
- Gravity
- Centrifugal load
- Generative
The designer applies specifications directly to the part, and the system generates the appropriate mathematical model using modeling techniques developed by analysts. You do not select a type of element nor worry about the appropriate modeling techniques. A single menu selection displays shaded stress contours (Von Mises stresses) on the deformed geometry.
- High speed
An extremely fast enervative capability creates the finite element model, computes the results and displays stress contours in seconds. After the meshing phase GPS indicates the estimated computation time. By knowing how long the solving will take, you can then reassess the strategy for any necessary adjustments. GPS also improves computation time thanks to sparse solver capability provided by CATIA V4 ELFINI Solver (ELF). This enables you to perform simulations on large or complex models without lengthy delays between results
- Accelerated design change handing
Design work can be greatly speeded up through the CATIA parameterization methodology. The designer can modify any geometry parameter and then update the solid and the analysis results in a single interaction.
- Extremely accurate
A unique technique for exact stress field recovery yields more accurate results than traditional methods. Some test cases have shown a 20 percent gain in accuracy. The system also presents distributed error information for you to better understand result accuracy.
