[Gmsh] Mesh 2d surface only with triangles.

[DILASSER Guillaume]

Hi César,

Do you have defined a Gmsh option file (.opt) either directly for your .geo file or globally ? 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,

Hi,

I cannot reproduce it. I open the geo with the GUI, click on Mesh->2D and get a triangular mesh.

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.
