One catch is that "outside" is determined by the local node ordering so that, if you're using an external mesh generator, you need to be sure that it orients them correctly so that outside is what you think it is. For example, Cubit has a "flip normal" function to do this. If you're using libMesh mesh generation, outside is what you think it is.
