PCHYPRESetInterpolations#
Set interpolation matrices for PCHYPRE type of ams or ads
Synopsis#
#include "petscpc.h"
PetscErrorCode PCHYPRESetInterpolations(PC pc, PetscInt dim, Mat RT_PiFull, Mat RT_Pi[], Mat ND_PiFull, Mat ND_Pi[])
Collective
Input Parameters#
pc - the preconditioning context
dim - the dimension of the problem, only used in AMS
RT_PiFull - Raviart-Thomas interpolation matrix
RT_Pi - x/y/z component of Raviart-Thomas interpolation matrix
ND_PiFull - Nedelec interpolation matrix
ND_Pi - x/y/z component of Nedelec interpolation matrix
Notes#
For AMS, only Nedelec interpolation matrices are needed, the Raviart-Thomas interpolation matrices can be set to NULL.
For ADS, both type of interpolation matrices are needed.
Developer Notes#
This automatically converts the matrix to MATHYPRE if it is not already of that type
