## 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
