# Finite Element Analysis Skill

## Purpose
Provide expert finite element analysis capabilities for aerospace structural analysis including static stress, buckling, and dynamic response.

## Capabilities
- NASTRAN, ABAQUS, ANSYS model setup
- Mesh generation and quality metrics
- Element type selection and justification
- Load case definition and combination
- Boundary condition specification
- Static stress analysis execution
- Buckling and stability analysis
- Results post-processing and margin calculation

## Usage Guidelines
- Select appropriate element types based on structural geometry and loading
- Verify mesh quality metrics meet aerospace standards
- Apply proper load factors per certification requirements
- Use correct material allowables for temperature and environment
- Calculate margins of safety using appropriate failure criteria
- Document all modeling assumptions and simplifications

## Dependencies
- MSC NASTRAN
- ABAQUS
- ANSYS
- HyperMesh
- Femap

## Process Integration
- AE-007: Finite Element Analysis Workflow
- AE-008: Fatigue and Damage Tolerance
- AE-009: Composite Structure Design
