DMCompositeSetCoupling

Sets user provided routines that compute the coupling between the seperate components (DMs) in a DMto build the correct matrix nonzero structure.

Synopsis

#include "petscdmcomposite.h"   
PetscErrorCode  DMCompositeSetCoupling(DM dm,PetscErrorCode (*FormCoupleLocations)(DM,Mat,PetscInt*,PetscInt*,PetscInt,PetscInt,PetscInt,PetscInt))

Logically Collective on MPI_Comm

Input Parameter

	dm	- the composite object
	formcouplelocations	- routine to set the nonzero locations in the matrix

Notes: See DMSetApplicationContext() and DMGetApplicationContext() for how to get user information into this routine
