PCHYPRESetEdgeConstantVectors#
Set the representation of the constant vector fields in the edge element basis for PCHYPRE of type ams
Synopsis#
#include "petscpc.h"
PetscErrorCode PCHYPRESetEdgeConstantVectors(PC pc, Vec ozz, Vec zoz, Vec zzo)
Collective
Input Parameters#
pc - the preconditioning context
ozz - vector representing (1,0,0) (or (1,0) in 2D)
zoz - vector representing (0,1,0) (or (0,1) in 2D)
zzo - vector representing (0,0,1) (use NULL in 2D)
Developer Notes#
If this is only for PCHYPRE type of ams it should be called PCHYPREAMSSetEdgeConstantVectors()
