[Gmsh] Physical Surfaces/volumes in unv format

Hello Folks,


I had a question regarding physical/volumes in unv format : 


I created a mesh in Salome (see attached file), and defined groups of faces
( their equivalent of physical surfaces). They are named 100, 102 and, 103.


I am not familiar with the structure of the unv files ( That  structure
seems to be one of the great mysteries of our time. It is very difficult to
find a simple document describing the format.)

However, when I look at the file, I can see these numbers appearing ( lines
1013, 1145 and 1157) in a section starting with 2467. Now, when I open the
file in gmsh 2.08 (windows) , I can only see one geometrical and one
physical surface !! 


For what it is worth : here is a discussion on the openfoam board of what
seems to be the same problem.


All the best,
