	)

Create a uniform mesh::Mesh over the rectangular prism spanned by the two points p. The order of the two points is not important in terms of minimum and maximum coordinates. The total number of vertices will be (n[0] + 1)*(n[1] + 1)*(n[2] + 1). For tetrahedra there will be will be 6*n[0]*n[1]*n[2] cells. For hexahedra the number of cells will be n[0]*n[1]*n[2].

Parameters

[in]	comm	MPI communicator to build mesh on
[in]	p	Points of box
[in]	n	Number of cells in each direction.
[in]	celltype	Cell shape
[in]	ghost_mode	Ghost mode
[in]	partitioner	Partitioning function to use for determining the parallel distribution of cells across MPI ranks

Returns
