PCHYPRESetDiscreteCurl#
Set discrete curl matrx for PCHYPRE type of ads
Synopsis#
#include "petscpc.h"
PetscErrorCode PCHYPRESetDiscreteCurl(PC pc, Mat C)
Collective
Input Parameters#
pc - the preconditioning context
C - the discrete curl
Notes#
C should have as many rows as the number of faces and as many columns as the number of edges in the mesh
Each row of G has as many nonzeros as the number of edges of a face, with column indexes being the global indexes of the corresponding edge: matrix entries are +1 and -1 depending on edge orientation with respect to the face orientation
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 ads it should be called PCHYPREADSSetDiscreteCurl()
