Design Space
Workflow to support topology optimization model build and setup.
Optimization
Setup an Optimization in HyperMesh.
Design Explorer
Multi-disciplinary design exploration and optimization tools.
Validate
Validate the model built before running solver analysis.
Analyze
Models require loads and boundary conditions in order to represent the various physics and/or physical equivalents to bench and in-use testing.
Axisymmetry
Reduce a full 3D model with axisymmetric surfaces while accounting for imperfections.
Concept Modeling
Tools and workflows that are dedicated to rapidly creating new parts for specific use cases, or amending existing parts. The current capabilities are focused on stiffening parts.
Crash and Safety
Tools used for crash and safety analysis.

  Use the IP Impact tools to automatically calculate the instrument panel (IP) testing area according to the regulations FMVSS201 and ECE-R21, position the headform impactor, and export ready-to-run solver decks for all the selected impact locations.
- Pedestrian Impact
  The Pedestrian Impact tool automates the vehicle marking, impactors positioning and the export of solver decks with minimal input, therefore reducing the full process lead time.
- FMVSS 201 U – Upper Interior Head Impact
  Use the Fmvss201U Marking tool to streamline the vehicle marking process by incorporating necessary input data for vehicle parts.

    - Injury
      The Injury menu offers calculations for all known injury assessment tools.
    - Units
      convert to/from common unit sets.
    - Miscellaneous
      Contains some functions that are not commonly used, such as simulating a bar chart or histogram.
    - Transforms
