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!
