I ended up drawing the volume in the gui and it still crash, but now for a different reason.
If I have the 8 corners of the box 1e-5 apart with a 5-e7 characteristic length the mesher crashes. If I have the 8 corners of the box 1 apart with a 0.05 characteristic length the mesher works. This is gmsh 2.0.8 packaged for Ubuntu for a amd64 machine. Is there a way to make this work without crashing?
