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

Static vs Dynamic Decision

Condition	Analysis Type
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

Feature	Learning Edition	Full License
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?"
