Verifiable challenge — Same force, more nodes
Complete 05_challenge.mac with mesh_h=0.025 m. Do not copy case IDs
from the previous case, and do not solve.
| Magnitude | Base case | Challenge |
|---|---|---|
| Elements | 40 | 320 |
| Nodes | 126 | 615 |
| Nodes per end | 6 | 15 |
| Constrained DOFs | 18 | 45 |
| Nodal force | −166.6667 N | −66.6667 N |
| Sum FY | −1000N | −1000N |
Before running, predict which columns should change and which should remain unchanged.
Then explain why force_per_node is not a separate physical input.
