Altair HyperCrash Capabilities
Quality
The Quality module evaluates the quality of the model by performing hundreds of different checks on the part, component and model level. A variety of checks are executed ranging from simple element checks to part connectivity and modeling errors in the input deck. Users visually review the state of each check represented by status color (red, orange and green).
- Model Cleaner
- Remove unused options
- Check connectivity for failed welds, unconnected parts and topology of connected parts
- Automatically remove initial penetrations
- Model Checker
- Exercises hundreds of unique checks
- Model robustness for crash worthiness criteria
- User defined criteria checks
- Optimize model per solver
Mesh Editing
Users can modify and edit crash meshes from within HyperCrash. There are many straightforward methods and options for editing and tuning a mesh for crash analysis. Mesh editing capabilities include but are not limited to:
- Adding, duplicating and moving nodes
- Creating 1D, 2D and 3D elements
- Create, modify and check rigid bodies
- Split parts or move elements from part to part
- Renumber selected entities, parts or the complete model
- Clean the model by removing unused entities
Safety Tools Module
This module provides a streamlined, user friendly interface to set-up, edit and define all safety related characteristics for crash simulation and analysis. In addition to the standard set of safety tools, HyperCrash contains a unique seat deformer utility that allows the seat foam, on both the lower and back of the seat, to be deformed based on the intersection between the dummy and the seat. Safety features include:
- Dummy positioning
- Interactively position dummy
- Save/retrieve dummy positions
- Seat belts
- Seat belt creator
- Seat belt routing
- Airbag toolset for creation and folding of airbags
- Seat deformer
- Deform the seat automatically to remove the initial intersections with the dummy.
Mass Balance
The Mass Balance module completely manages the mass and inertia properties of each part as well as the entire crash model. After the masses are set for all parts and components HyperCrash automatically balances the total mass of the model according to the mass on the front and rear tires. In addition, HyperCrash can:
- Display the center of mass locations for each part, rigid body and the complete model
- Check and report the mass, inertia and center of mass location of each part, component and rigid body of the model
- Automatically fits the finite element model mass of each part based on the mass of the CAD part
- Mass will be created if necessary
