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.
