[Gmsh] Getting a graded mesh metric

[Jiplea, Marius]

Hello again,

I am trying to mesh the surface of the ocean in a graded way. I'd like the mesh to be fine (small) near the shore and coarse (large) as we go far from the shore. I'm using compound lines in order to avoid getting a mesh near the shorelines that is smaller then the one I wish to obtain.

I know that by using a threshold field I should be able to control the gradation of a mesh, but it seems that it does not work (maybe because I'm using compound lines?).

Kind Regards,
Mihai
