Challenge: double the load
| Case | Total force | uy_tip (MAPDL) | Ratio |
|---|---|---|---|
| Base | −1000 N | your result | — |
| Modified | −2000 N | your result | uy_2000 / uy_1000 |
Acceptance criterion: ratio between 1.99 and 2.01.
Critical question
Why does this test not prove by itself that the model is correct?
A model can respond linearly and still contain incorrect units, constraints, material, or loads. APDL can automate the analysis, but it cannot replace engineering judgement.
