# FESA Abaqus Subset

Use this skill when parser scope, input compatibility, Nset/Elset handling, or unsupported keyword behavior is involved.

## Read First

- `/AGENTS.md`
- `/PROGRESS.md`
- `/PLAN.md`
- `/docs/ABAQUS_INPUT_SUBSET.md`
- `/docs/NUMERICAL_CONVENTIONS.md`
- `/docs/ARCHITECTURE.md`
- `/docs/VERIFICATION_PLAN.md`

## Workflow

1. Map each requested keyword to the documented Phase 1 subset.
2. Check `*Nset` and `*Elset` semantics, ordering, generated sets, and use by boundary/load/result requests.
3. Keep Abaqus keyword parsing separated from internal object creation through Factory + Registry.
4. Require explicit diagnostics for unsupported keywords instead of silent partial parsing.
5. Record parser-scope changes in ADRs or subset docs when they affect project policy.

## Do Not

- Do not silently expand support beyond the documented subset.
- Do not store parser-only details in solver core objects unless the architecture document requires it.
