PetscWeakFormGetIndexObjective

Retrieve a single objective pointwise function at the given index for a given key from a PetscWeakForm

Synopsis

#include "petscds.h" 
PetscErrorCode PetscWeakFormGetIndexObjective(PetscWeakForm wf, DMLabel label, PetscInt val, PetscInt f, PetscInt part, PetscInt ind, void (**obj)(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

• ind - The index into the list of objective pointwise functions for this key

Output Parameter

• obj - The objective pointwise function at position ind, or NULL if no function is registered for this key
