Abaqus Master Skill
Master orchestrator for all Abaqus FEA tasks. Routes requests to specialized skills based on user intent.
When to Use This Skill
You are here because the user mentioned FEA, Abaqus, structural analysis, or simulation. Your job is to:
- Understand what the user wants
- Route to the appropriate specialized skill
- Ask clarifying questions if unclear

| Load applied slowly, constant | Static |
| Load varies with time | Dynamic |
| Inertia effects important | Dynamic |
| Finding mode shapes only | Modal |
| Pre-stress then modes | Static + Modal |
What to Ask If Unclear
Missing Analysis Intent
"What do you want to find out? Options:
- Stress and displacement (static analysis)
- Natural frequencies (modal analysis)
- Impact/crash response (dynamic analysis)
- Temperature distribution (thermal)"
Missing Geometry
"What are the dimensions of your part?"
Missing Constraints
"How is the structure supported? (fixed, pinned, roller)"
Missing Loads
"What loads are applied? (force, pressure, displacement)"
Ambiguous Optimization
"What kind of optimization?
- Topology: Redistribute material, add holes (requires full license)
- Shape: Modify surface only, reduce stress concentrations"
Required Information by Analysis Type
| Analysis | Geometry | Material | BCs | Loads | Extra |
|---|
| Static | Yes | Yes | Yes | Yes | - |
| Modal | Yes | Yes (with density) | Yes | No | Number of modes |
| Dynamic | Yes | Yes (with density) | Yes | Yes | Time period |
| Thermal | Yes | Yes (conductivity) | Yes | Heat/convection | - |
| Topology | Yes | Yes | Yes | Yes | Volume fraction |
| Contact | Yes | Yes | Yes | Yes | Contact pairs |
License Limitations

| Max nodes | 1000 | Unlimited |
| Static analysis | Yes | Yes |
| Modal analysis | Yes | Yes |
| Topology optimization | No | Yes (Tosca) |
| Shape optimization | No | Yes (Tosca) |
If user has Learning Edition + optimization request:
"Topology optimization requires a full Abaqus license with Tosca. Would you like a static analysis instead?"
