Geometry and mesh

Two plates separated by interface_gap=0.1 mm with a consistent mesh.

Step 1 — Geometry and mesh

BLOCK,0,plate_x,0,plate_t,0,plate_z
BLOCK,0,plate_x,plate_t+interface_gap,2*plate_t+interface_gap,0,plate_z
VMESH,ALL

Document interface_gap in the README and CSV. Confirm that there is no unintended continuity between the plates.
