It's not currently implemented, but you're welcome to do so. The current periodic meshes are built in a roundabout way: to build a 2d periodic mesh, a torus is constructed (this has the desired connectivity but not the desired geometry), then the coordinates are replaced by the coordinates of a rectangle. Related: there must be a way to build these directly, rather than via the hack? I continued using the hack because I didn't know how to build a mesh without going through mesh._from_cell_list.

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?

Cheers, Daniel
