I suggest you define your volume to be a "physical volume". Once any 
physical items are present in the geometry, only those physical items 
are exported in the mesh. I.e. if you don't mark the boundary as 
physical as well, the triangles of the boundary will not be exported 
separately.

Hope this helps.
