I looked through the source code of the Gmsh API and found that the .geo_unrolled extension is supported for the gmsh.write() function, but not just .geo. This extension does the trick mostly, but it seems that any meshing operations (such as marking curves as transfinite) or transformations (such as dilate) are not written to the output file ...

I am using gmsh 2.0.0. When trying to mesh the attached geometry (tmp1.geo), I manage to have structured meshes on surfaces #50 and #61. But when I try to mesh tmp2.geo, which includes tmp1.geo, gmsh says those surfaces cannot be meshed with the transfinite algorithm. I have the same problem with the new surfaces (#75 --> #82) declared in tmp2.geo.
