[Gmsh] Compatible mesh - Import step geometry

[Zenker, Matthias]

Hi,

I had (and still have) the same problem (haven't worked with gmsh for some time, but the problem will pop up again when I restart).
I am using elmerfem for my simulations. The mesh import can be told to remove duplicate and closely neighboring points in meshes to a certain degree. But this function has its limits, especially when the mesh widths differ.
Wasn't there a patch in gmsh permitting to clean up duplicate faces?
AFAIK it is not possible in a 3D CAD model in STEP format to do that (at least that is what my colleagues using SolidWorks say), so it would have to be done by processing the imported STEP geometry in gmsh.

A solution within gmsh would be most useful.
