In other words, after applying your transformation function to a boundary node, do you end up at one of your periodic nodes within tolerance? If not, then you have a problem with your mesh. FWIW, I have seen other meshes generated in Cubit that fail the conditions necessary for applying periodic boundaries. Have you tried using the mesh generation functions in libMesh to give you a working tet mesh?
