PCHYPRESetBetaPoissonMatrix#

Set Poisson matrix for PCHYPRE of type ams

Synopsis#

#include "petscpc.h" 
PetscErrorCode PCHYPRESetBetaPoissonMatrix(PC pc, Mat A)

Collective

Input Parameters#

  • pc - the preconditioning context

  • A - the matrix, or NULL to turn it off

Note#

A should be obtained by discretizing the 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 PCHYPREAMSPCHYPRESetBetaPoissonMatrix()
