Detailed Description

Build a distributed NxNxN hex mesh. Each rank owns one NxNxN block. Blocks are stacked in the X direction: rank p has X in [p*N, (p+1)*N]. Node ownership: rank p owns nodes with X in [p*N, (p+1)*N), except the last rank also owns X = np*N. Shared boundary nodes at X = p*N are owned by rank p.

Global cell index: rank-contiguous. Rank p's cells are [p*N^3, (p+1)*N^3). Cell (ix, iy, iz) on rank p → global index = p*N^3 + ix*N*N + iy*N + iz.

Global node index: rank-contiguous. Rank p owns nodes with ix in [0, N) (or [0, N] for last rank), iy in [0, N], iz in [0, N]. Local node (ix, iy, iz) → local index = ix*(N+1)*(N+1) + iy*(N+1) + iz. Global index = rank-offset + local index.
