# SOL 101 — Static Analysis
**Simulation:** Beam_sim1.sim
**Solver:** NX Nastran SOL 101 (Linear Static)
**Status:** Pending gap resolution
---
## Setup
| Item | Value | Notes |
|------|-------|-------|
| Solution type | SOL 101 (Linear Static) | Appropriate for this problem |
| Element type | ❓ TBD | Gap G8: CQUAD4/CQUAD8 (shell) or CTETRA/CHEXA (solid)? |
| Mesh density | ❓ TBD | Gap G8: convergence checked? |
| Loading | ❓ TBD | Gap G2: point load? distributed? self-weight? |
| BCs | ❓ TBD | Gap G1: cantilever? simply-supported? |
## Result Extraction
| Output | Method | Expression/Sensor | Status |
|--------|--------|-------------------|--------|
| Mass | NX expression | `p173` | ✅ Known |
| Tip displacement | ❓ Sensor or .f06 parse | TBD | Gap G3, G6 |
| Von Mises stress | ❓ Sensor or .f06 parse | TBD | Gap G4, G6 |
## Solver Considerations
*From Technical Breakdown:*
- **Linear assumption:** 22 mm displacement on likely 2+ m beam → L/δ probably OK. Verify.
- **Mesh sensitivity:** Stress at hole edges is mesh-dependent. Need convergence check (Gap G8).
- **Mesh morphing vs remesh:** Parametric NX models typically remesh on update. Need to confirm behavior across DV range (Gap G7).
- **Runtime estimate:** Single beam, ~10K–100K DOF → probably seconds to low minutes per evaluation.
## Validation Checklist
- [ ] Baseline mass matches NX expression `p173`
- [ ] Baseline displacement matches reported ~22 mm
- [ ] Mesh convergence verified at baseline
- [ ] Mesh quality acceptable at DV range extremes
- [ ] Model rebuilds cleanly at all 4 corners of design space
## History
- **Gen 001** (2026-02-09): Initial documentation from technical breakdown. All solver details pending gap resolution.
