Hi Andrew, Hope all is well. I'd wager on the extrude function rather than gmsh import as being the source of the problem. I wrote that when you were here that time and I haven't looked at it since. One thing to do is to create a 3D mesh in gmsh and use that without using the extrude function. Have you already tried that? I'm going to look into it, but anything you have will be helpful. > I also recall there being problems plotting hexahedrons in mayavi. Is this > true, or am I imagining this?

Yeah, we had problems with cell vertex ordering when we wrote the mayavi viewer. I'm not sure we ever sorted that one out so any code you have that deals with that issue would be very helpful.
