Prediction — What happens before SOLVE?
Two 40 × 40 × 20 mm blocks with an initial 0.5 mm gap.
| Quantity | Value | Interpretation |
|---|---|---|
| Initial gap | 0.0005 m | Open pair in CNCHECK |
| Case 1 displacement | −0.0002 m | Does not close the gap → no load transfer |
| Case 2 displacement | −0.0012 m | Closes the gap and compresses → support reaction |
| Topology | 150 nodes / 64 solids / 16+16 contact | Mesh consistent with mesh_h = 0.01 m |
Prediction: with disp = −0.2 mm, contact remains open (contact_closed = 0). With disp = −1.2 mm, it must close and produce a vertical reaction at the lower support.
