#include "petscfv.h" 
PetscErrorCode PetscFVRefine(PetscFV fv, PetscFV *fvRef)

- fv - The initial - PetscFV
Output Parameter#
- fvRef - The refined - PetscFV

This is typically used to generate a preconditioner for a high order method from a lower order method on a refined mesh having the same number of dofs (but more sparsity). It is also used to create an interpolation between regularly refined meshes.
