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! ~Gmsh User _______________________________________________ gmsh mailing list [email protected] http://www.geuz.org/mailman/listinfo/gmsh
