<p style="margin-top:0;margin-bottom:0">I have three concentric cylinders. The first physical volume that I want to define is the volume between the outer most cylinder and the middle cylinder. The second physical volume that I want to define is the volume
between the middle cylinder and the inner most cylinder. When I run this script gmsh tells me that there are subfaces intersecting and crashes. How can I fix this script? Could this be a possible bug?</p>
