#include "petscvec.h"   
PetscErrorCode PetscSectionSetClosurePermutation(PetscSection section, PetscObject obj, IS perm)

Input Parameters

section - The PetscSection
obj - A PetscObject which serves as the key for this index
perm - Permutation of the cell dof closure

Note: This strategy only works when all cells have the same size dof closure, and no closures are retrieved for other points (like faces).
