Fabio - I never use the unv file format myself, but IIRC Gmsh uses a
group "790" (whatever that means) to save its physical entities. Right
now there is no support for saving anything else than the number of the
entities, though.

Let us know if you generalize the unv export routine (in 
Mesh/Print_Mesh.cpp): other people on this list have expressed interest 
for similar things in the past.

Take care,

Christophe
