PetscWeakFormAddResidual

Append residual pointwise functions f0 and f1 to the lists for a given key in a PetscWeakForm

Synopsis

#include "petscds.h" 
PetscErrorCode PetscWeakFormAddResidual(PetscWeakForm wf, DMLabel label, PetscInt val, PetscInt f, PetscInt part, 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[]), 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

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

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