That's right: the .msh file is the only info passed from Gmsh to GetDP.

Not that I know of. Unless you can use an existing formulation (see e.g.
http://geuz.org/getdp/wiki), you really need to know the mathematics of
the problem (and have a good understanding of the finite element method) 
in order to write a formulation in GetDP.

No. You can generate such docs from the source code if you want, but I
don't think they will be very useful: GetDP is written in a rather
general way (there is absolutely no "physics" in the code)--the actual
problems are completely defined in the ".pro" files.

Do you have a particular feature in mind?
