		int	Part_amount,
		int	Parition_tool
	)

----------------------------------------------------------- mmpr_partition_mesh - to to decompose the mesh and create subdomains by Metis (SFC - Parmetis) library ------------------------------------------------------------

int mmpr_adaptive_repartition

(

int

Mesh_id

)

----------------------------------------------------------- mmpr_adaptive_repartition - to balance the work load of a graph that corresponds to an adaptively refined mesh ------------------------------------------------------------

void mmpr_create_overlap

(

const int

MeshID

)

----------------------------------------------------------- mmpr_create_overlap - create overlap, fill data structure, set internal ------------------------------------------------------------

void mmpr_end_work

(

)

----------------------------------------------------------- mmpr_end_work - free memory for internal data structures ------------------------------------------------------------

void mmpr_init_data	(	int	Mesh_id,
		int	Part_amount
	)

----------------------------------------------------------- mmpr_initialize_work - to initialize the internal data structures ------------------------------------------------------------

int mmpr_IPC_expand_overlap

(

const int

Mesh_id

)

----------------------------------------------------------- ddr_expand_overlap - to expand overlap regions by one element layer ------------------------------------------------------------

Here is the call graph for this function:

		const int *	ElemsChanged,
		const int	nElems
	)

----------------------------------------------------------- ddr_update_overlap - to update one element overlap layer ------------------------------------------------------------
