[Gmsh] cannot change the meshing size

[Zhang, Fangyin]

Hi Christophe,

I have tested the .geo file on a Linux machine, the file works as expected. Seems the problem lies in the Windows version of Gmsh.

When I tried to mesh the lines, no matter what kind of meshing size I defined (by changing the “Prescribed mesh element size at point”, which is the parameter “cl1” in the attached file, and through “Mesh à Define à Size at points”), the element size is always the same.

Your file works as expected here. Maybe you're just not looking at the 1D mesh (it's not displayed by default)? Double-click in the graphic window and select "Mesh visibility->Nodes" and/or "mesh visibility->1D elements".
