[Gmsh] Problems with a 3D STEP file: cannot generate a conformal mesh

[Zenker, Dr. Matthias]

Hi,

I have problems meshing a 3D STEP geometry (see attachment). I cannot
generate a mesh which is continuous at the interfaces so that no heat
can flow between the 3 bodies contained in the model. 
I have tried to "heal" the geometry using netgen, and import the result
into gmsh to generate the mesh, but it was still noncontinuous.
In the message window I have seen that gmsh (2.5.1) also performs some
"healing" (but surfaces are not sewed as in netgen), but this apparently
does not help here. When I generate the mesh in netgen, I get a
continuous mesh, but I would prefer to generate the mesh with gmsh. 
This is a simplified test geometry - for a more complicated geometry, I
get a crash in netgen, and gmsh complains about overlapping faces.

Any idea how I can generate a continuous mesh in this case?

Thank you,

Matthias
