HI,

I would try once again to do the meshing in gmsh for the whole geometry. Even if you mesh your wires one by one, you still have to connect the resulting mesh to the outer volume, passing from a very fine mesh to a coarser one. BTW I wonder how ElmerGrid does that.
Did you try the different meshing algorithms provided by gmsh?
You could also post this question on the gmsh mailing list, I think Christophe Geuzaine can help you.

HTH,

Matthias

Hi Robert,
1. If you continue with gmsh, you can do along the way which Matthias suggests in the previous post.
2. By chance, if you happen to use Salome preprocessor, some preliminaries for multiple bodies geometry and meshing are discussed in viewtopic.php?f=2&t=3644&sid=f45fd2d43e ... 4fbf15d284.

Yours Sincerely,

Hi,

to my experience, Salomé has quite some strong points, but specifically in meshing it does not do a better job than gmsh. Only netgen is available in 3D, whereas gmsh has several algorithms to choose.
But of course one can always try if by chance this specific case can be better handled in Salomé.
