Hello everyone,

I have a little issue creating my unstructured mesh on gmsh.
I would like to simulate a pipe flow and for that I need to refine the Walls of the pipe, in order to have more accurate calculations at the edge and larger calculations at the center.


I tried with "Transfinite" but as soon as I put both edges (Top & Bottom) as "Transfinite curve", I just get the same small mesh everywhere.

I've heard there might be a way with "Field[] = Attractor", but I couldnt figure it out yet...


Any Idee? Thanks!


Edit:

I have managed to create the mesh and refine on both edges, but as soon as I try to gather them together with the commands :

Field[] = Min;
Field[].FieldsList = { , };
Background Field = ;

, the result is a very fine mesh over the entire surface (except at Inlet and Outlet)
