Functions
void	iMeshP_getCommunicator (iMesh_Instance instance, int *fcomm, MPI_Comm *ccomm, int *err)
	Convert a fortran to C communicator Given a Fortran communicator, convert to a C communicator that can be passed back to iMeshP. Though this is an iMeshP function, it doesn't take an iMeshP Partition handle, since the (C) communicator is needed by the function that creates the partition. COMMUNICATION: None.
void	iMeshP_assignGlobalIds (iMesh_Instance instance, const iMeshP_PartitionHandle partition, const iBase_EntitySetHandle this_set, const int dimension, const int start_id, const int largest_dim_only, const int parallel, const int owned_only, int *err)
	Assign a global id space to entities Assign a global id space to entities and vertices, and optionally intermediate-dimension entities.

void iMeshP_getCommunicator	(	iMesh_Instance	instance,

		MPI_Comm *	ccomm,

	)

Convert a fortran to C communicator Given a Fortran communicator, convert to a C communicator that can be passed back to iMeshP. Though this is an iMeshP function, it doesn't take an iMeshP Partition handle, since the (C) communicator is needed by the function that creates the partition. COMMUNICATION: None.

Parameters:

instance	(In) Mesh instance to contain the partition.
fcomm	(In) Pointer to fortran communicator
ccomm	(Out) Pointer to the C communicator
err	(Out) Error code.
