<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I've imported a CAD geometry (same problem with IGES and
STEP). The file is an assembly of two parts. When I open it in gmsh everything
works fine. gmsh shows two volumes and when I am doing the surface mesh (2D) I
get a perfect mesh. The contact surface of the two volumes is meshed as well,
that is exactly what I want. But when I try to do volume meshing gmsh crashes.
In the Linux version without a message. In the windows version with the
following message:</FONT></DIV>

<DIV><FONT face=Arial>The error occurs with all tested assembly files that
consinst of multiple volumes. Perhaps someone can help!</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>The goal is to mesh a assembly consisting of two parts.
And the contact surface of the volumes should be meshed as surface. Like gmsh
does in the surface meshing step described above. But the 3D meshing
crashes.</FONT></DIV>
