- Crack Growth Fatigue Module
  Use the fatigue module to configure strain life fatigue evaluation necessary for Auto Hotspot detection.
  - Configure Fatigue Analysis
    Use the CG tool to calculate fatigue based on the strain-life uniaxial method.
- Materials
  Use the Material tool to associate predefined or user-generated materials with the model's parts and sets.
- Load Maps
  Use the Load Map tool to create multiple channels (load histories) which are then paired with subcases/loadsteps to create the fatigue events.
- Hotspots
  Nodal hotspot are used to assign crack properties.
Evaluate
Run the model and view results.
