Study 03 — Robustness Checks
Type: Parametric — Specific Scenarios Runs: 8 Model: Uses both .sim setups (CBUSH for K tests, displacement for correlated tests) Prerequisite: Complete Studies 01 and 02 first (needs knee values)
What This Does
Tests scenarios that the simple sweeps can't capture:
- One-soft-point (3 runs): What if one support is 10× softer than the rest?
- Combined compliance (3 runs): Both vertical and lateral at knee values simultaneously
- Correlated displacement (2 runs): All verticals move together (frame bending mode simulation)
Before Running
Update atomizer_spec.json with actual knee values from Study 02:
- Replace
KNEEplaceholders with K_vert_knee and K_lat_knee values - Replace
KNEE/10with knee/10,KNEE/2with knee/2
Output
- Interaction factor: is combined ΔWFE > sum of individual?
- Worst-case single soft point identification
- Correlated vs independent displacement comparison
