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()
