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
