PetscFVRefine
Create a "refined" PetscFV object that refines the reference cell into smaller copies. This is typically used to precondition a higher order method with 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.
