[Gmsh] meshing the hole containing compound body

[Nima Naraghi]

Dear Sir/Madam

I am trying to model Induction Heating problem and I am using GMSH 2.5
(windows) to define and mesh my geometry. As you know since further more I
will need curl of magnetic potential field as the base for solving PDEs, I
want my mesh to be as accurate and fine as possible.

However as I try to mesh it it gives me self intersecting surfaces error,
due to the fact that my surrounding cube has two holes which one of them
consists of two bodies connecting to each other(different materials).
Could you please take a look at my attached .geo file and let me know how I
can solve this problem?

Many thanks in advance.

Kind Regards,
Nima
