hex_mesh_cells meshes cells that meet face to face (SolidCraft split bodies) as one conforming all-hex mesh: each cell a mapped block after smoothly meeting faces are joined (virtual topology: the halves of a hole, a plane running into a fillet), vertices, edges and faces shared by identity, interval assignment over all cells, each shared face meshed once, radial edges graded off curved faces. finish spans several cells: tags per cell, hex20 mid-edge nodes shared across cells, a closed 2-manifold boundary and no free internal face.
