PCBDDCSetDofsSplittingLocal

Set index sets defining fields of the local subdomain matrix

#include "petscpc.h" 
PetscErrorCode PCBDDCSetDofsSplittingLocal(PC pc,PetscInt n_is, IS ISForDofs[])

Collective

	pc	- the preconditioning context
	n_is	- number of index sets defining the fields
	ISForDofs	- array of IS describing the fields in local ordering

n_is should be the same among processes. Not all nodes need to be listed: unlisted nodes will belong to the complement field.
