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:

1. Understand what the user wants

2. Route to the appropriate specialized skill

3. Ask clarifying questions if unclear

| 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"
