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 Note#

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()
