Hi Matt,
have you had a look at http://geuz.org/gmsh/doc/texinfo/gmsh-full.html#SEC42 and
http://geuz.org/gmsh/doc/texinfo/gmsh-full.html#SEC64 ?
...
In the MSH file format (see section 9. File formats), if physical entities are defined, the output mesh only contains
those elements that belong to physical entities.
...
Cheers,
Dave
