Hi Guillaume, Matthias and Paul.I found the file .gmsh-options and I removed it. I think that I saved it accidentaly and I did not know that I had it.
Now I have only triangles in the mesh. So the problem is solved.
 Thank you.Regards.

If so, check that this file does not have an option forcing Gmsh to use quads, like for example Mesh.RecombineAll = 1 ;. To me, that is the only thing that can be happening because, by default, your .geo should give you a triangular mesh…    Sincerely Yours,    Guillaume DILASSER Doctorant DACM / LEAS CEA - Centre de Saclay - Bât.123 - PC 319c 91191 Gif sur Yvette Cedex - France -    guillaume.dilasser at cea.fr    De : gmsh [mailto:gmsh-bounces at ace20.montefiore.ulg.ac.be]De la part de Zenker, Dr. Matthias

Betreff: [Gmsh] Mesh 2d surface only with triangles.    Dear partners, I want a mesh with only triangles, but I get also quads. It is a 2d geometry. How can I force gmsh to use only triangles? I have attached a geo file as example. Regards.
