NLGEOM and substeps

KBC,0, NSUBST=10, OUTRES,ALL,ALL, and verification that n_sets=n_substeps.

Step 2 — Enable NLGEOM and substeps

Substeps and convergence iterations — Figure 2. Ramp with 10 substeps; each may require several equilibrium iterations.

After solving, verify in POST1: *GET,n_sets,ACTIVE,0,SET,NSET must equal 10. Look in the .out file for completed convergence messages without aborts.

Deformed shape with NLGEOM ON under the same load as the linear baseline — Figure 4. `NLGEOM ON` deformed shape (same load). Compare it with the preceding figure, not only with the CSV.
