PetscWeakFormGetResidual

Retrieve the lists of residual pointwise functions f0 and f1 for a given key from a PetscWeakForm

Synopsis

#include "petscds.h" 
PetscErrorCode PetscWeakFormGetResidual(PetscWeakForm wf, DMLabel label, PetscInt val, PetscInt f, PetscInt part, PetscInt *n0, 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 *n1, 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[]))
