Projecting to Q works for me, but as Martin points out, this is
something that has been fixed in the development version.

Depends on what you want. The topological dimension is whether you
have intervals, triangles or tetrahedra. The geometric dimension is
the number of coordinates you have for the vertices. The boundary of a
3D tetrahedral mesh is a mesh with topological dimension 2 but
geometric dimension 3 (it's embedded in 3D).
