Hi, I dont' know the answer to your question, but here is what you can do to find it out: Open your msh file with a text editor and delete all tetrahedrons manually. Don't forget to adjust the number of entities accordingly. When you open the file with gmsh, I think you will see immediately where the triangles are.

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
