PCPatchSetComputeFunctionInteriorFacets

Set the callback used to compute facet integrals for patch residuals

Synopsis

#include "petscpc.h" 
PetscErrorCode PCPatchSetComputeFunctionInteriorFacets(PC pc, PetscErrorCode (*func)(PC, PetscInt, Vec, Vec, IS, PetscInt, const PetscInt *, const PetscInt *, void *), void *ctx)
Logically collective on PC

Input Parameters

pc - The PC
func - The callback
ctx - The user context

Calling sequence of func

  func (PC pc,PetscInt point,Vec x,Vec f,IS facetIS,PetscInt n,const PetscInt* dofsArray,const PetscInt* dofsArrayWithAll,void* ctx)

pc - The PC
point - The point
x - The input solution (not used in linear problems)
f - The patch residual vector
facetIS - An array of the facet numbers
n - The size of dofsArray
dofsArray - The dofmap for the dofs to be solved for
dofsArrayWithAll - The dofmap for all dofs on the patch
ctx - The user context

Notes

The entries of F (the output residual vector) have been set to zero before the call.
