PCHYPRESetAlphaPoissonMatrix#
Set vector Poisson matrix for PCHYPRE of type ams
Synopsis#
#include "petscpc.h"
PetscErrorCode PCHYPRESetAlphaPoissonMatrix(PC pc, Mat A)
Collective
Input Parameters#
pc - the preconditioning context
A - the matrix
Note#
A should be obtained by discretizing the vector valued Poisson problem with linear finite elements
Developer Notes#
This automatically converts the matrix to MATHYPRE if it is not already of that type
If this is only for PCHYPRE type of ams it should be called PCHYPREAMSSetAlphaPoissonMatrix()
