Dear Firedrakers, I am trying to set up a 3D cube mesh, periodic in all three directions, but can't find the correct class to call. At http://firedrakeproject.org/_modules/firedrake/utility_meshes.html only 2d periodic meshes are listed. Essentially, I'd like something like PeriodicUnitCubeMesh. How do I generate a mesh like this?
