[Gmsh] Step Import Non Conformal Mesh

[faber.mueller at t-online.de]

Hi,

Thank you very much for your answer. Boolean Fragments applied on the overlapping Volumes (even if they didn't seem to overlap on the first view) healed my geometrie and I finally received a conformal mesh from my step import. 
So now I can go on with getdp. 

Thanks and have a nice weekend,
Fabian

Hi,

If your volumes are somehow overlapping and give a nonconformal mesh, then you need to heal the geometry and you will probably have to 
reconstruct the volumes. But Gmsh version 3 gives you more powerful tools to edit the geometry, see
