This variable controls how the grid points are mapped to a linear array for global arrays. For runs that are parallel in domains, the local mesh order may be different (see MeshLocalOrder). The default is blocks when serial in domains and cube when parallel in domains with the local mesh order set to blocks.
The grid is mapped using small parallelepipedic grids. The size
of the blocks is controlled by MeshBlockSize.
The original order of the indices is used to map the grid.
The grid is mapped using a full cube, i.e. without blocking.
