Hi again!
I think I have managed to get what I wanted.
First, I made a tetrahedron "helpMesh" that spans a 3d domain.
Then I made an empty "mymesh" and copoied only the points from helpMesh.
Then I looped through the convexes and faces of helpMesh, for each face adding a
2d triangle as a convex in mymesh. By using the add_convex function I don't get
more than one of each face.
So "mymesh" spans a 3d domain, but its convexes are 2d triangles. The global
convex index on this mesh provides what I wanted.
I will also get a global index for the edges by using the NEDELEC(2) FEM on this
mesh, so I pretty much have what I want now. The base_point for each DOF will
allow me to find the orientation of each edge, which I will also need.

Dear Torquil,
What is your goal ? Only to number the faces (in that case, you can make
a loop on all faces and add it to the mesh and retain the number) or
something more complex ?
