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
