gmsh mesh manipulations with small lengths
Posted: 19 Oct 2011, 19:36
Hi all,
I use gmsh to produce the meshes I use in elmer. I am currently trying to obtain a very small, 10^-6 or less, characteristic length (with box or boundary layer fields) in a specific area of the mesh.
I have managed to control specific areas of the mesh with the box field for test cases of larger structures and characteristic lengths, but these fields seem to be having no effect on the mesh if the lengths are small. So I wonder if anyone with else has experienced this or could suggest anything that could help?
