PetscWeakFormSetIndexResidual

Set the residual pointwise functions f0 and f1 at the given indices for a given key in a PetscWeakForm

Synopsis

#include "petscds.h" 
PetscErrorCode PetscWeakFormSetIndexResidual(PetscWeakForm wf, DMLabel label, PetscInt val, PetscInt f, PetscInt part, PetscInt i0, void (*f0)(PetscInt, PetscInt, PetscInt, const PetscInt[], const PetscInt[], const PetscScalar[], const PetscScalar[], const PetscScalar[], const PetscInt[], const PetscInt[], const PetscScalar[], const PetscScalar[], const PetscScalar[], PetscReal, const PetscReal[], PetscInt, const PetscScalar[], PetscScalar[]), PetscInt i1, void (*f1)(PetscInt, PetscInt, PetscInt, const PetscInt[], const PetscInt[], const PetscScalar[], const PetscScalar[], const PetscScalar[], const PetscInt[], const PetscInt[], const PetscScalar[], const PetscScalar[], const PetscScalar[], PetscReal, const PetscReal[], PetscInt, const PetscScalar[], PetscScalar[]))

Not Collective

Input Parameters

• wf - The PetscWeakForm

• label - The label selecting the mesh region, or NULL for the entire domain

• val - The label value selecting the mesh region

• f - The field number

• part - The equation part, or 0 if unused

• i0 - The index at which to store f0 in the f0 list

• f0 - The f0 residual pointwise function; a NULL is ignored

• i1 - The index at which to store f1 in the f1 list

• f1 - The f1 residual pointwise function; a NULL is ignored
