Error Meshing Simple Volume
I've created a simple arrangement of two volumes ("air" and "inductor"), where the inductor is contained inside of the air volume, but extends to the edge of the domain (originally derived from onelab's cohomology indheat.geo example) -- see the attached file.
I'm not sure why exactly this setup is used in indheat.geo, but it looks like the surface ends of the two inductor terminals ("in" and "out") are removed from the surface of the air cube, and then the air volume is essentially assembled from the 6 cube faces plus the surface of the inductor.
Regardless, when I try to run the attached script in gmsh, it does not mesh the air volume -- and I cannot figure out why, since the setup seems functionally equivalent (though, simpler) to that of inheat.geo.
Any idea of why this geometry will not mesh properly?
