parmetis_partgeom()

subroutine, public parmetis::parmetis_partgeom	(	type(mesh_t), intent(inout)	msh,
		type(mesh_fld_t), intent(inout)	parts
	)

Parameters

[in,out]	msh	Mesh
[in,out]	parts	Partitions

parmetis_partmeshkway()

subroutine, public parmetis::parmetis_partmeshkway	(	type(mesh_t), intent(inout)	msh,
		type(mesh_fld_t), intent(inout)	parts,
		type(mesh_fld_t), intent(in), optional	weights,
		integer, intent(in), optional	nprts
	)

Parameters

[in,out]	msh	Mesh
[in,out]	parts	Partitions
[in]	nprts	Number of partitions

Note

We use C-style numbering in the element distribution. Otherwise, the partitions return by Metis will not be numbered in the same way as the MPI ranks
