PCHYPRESetInterpolations

Set interpolation matrices for AMS/ADS preconditioner

Synopsis

#include "petscpc.h" 
PetscErrorCode PCHYPRESetInterpolations(PC pc, PetscInt dim, Mat RT_PiFull, Mat RT_Pi[], Mat ND_PiFull, Mat ND_Pi[])
Collective on PC

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.
