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:

1. One-soft-point (3 runs): What if one support is 10× softer than the rest?
2. Combined compliance (3 runs): Both vertical and lateral at knee values simultaneously
3. 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 KNEE placeholders with K_vert_knee and K_lat_knee values
• Replace KNEE/10 with knee/10, KNEE/2 with knee/2

Output

• Interaction factor: is combined ΔWFE > sum of individual?
• Worst-case single soft point identification
• Correlated vs independent displacement comparison
