Hello,
Hopefully my answer would be helpful.
1. All Tri.s are on the boundary.
2. The 2nd "tag" of each Tri., the "geometric entity", tells you which
boundary surface the Tri. belongs to.
(find "number-of-tags" on this page
http://geuz.org/gmsh/doc/texinfo/gmsh.html )
3. You may see the "geometric entity index" of all boundary surfaces in
gui of gmsh via enabling "Tools/Options/Geometry/Surface numbers".

I think I am not understanding what you meant my Tri.s . Is this an operator or
something?
Could you clarify what you meant by that?
Just to give you more info about what I am actually doing, after I finish
meshing a geometry, I save the mesh in .msh file format and export it to MATLAB.
This is the only file I have, and this file clearly contains nodal numbers and
coordinates of bunch of triangles along with that of points, lines and
tetrahedrons. I need nodal numbers and coordinates of SURFACE TRIANGLES ONLY,
and my question was whether the triangles appearing in .msh file are indeed the
SURFACE TRIANGLES ONLY.
I am sorry if this is what you meant, but a clarification would certainly help.
Thanks for replying!
