Hi everyone,

I am trying to use deal ii to solve Helmoltz equation in a 2D heterogeneous
media. So I try to work with step-5, step-7 and step-29.

First I want to design my media using GMSH. I think I have succeeded.
Unfortunately when I want to implement my media in step-5 (just for a
test), my icpc compiler says:

The violated condition was:
    (version >= 2.0) && (version <= 2.1)

So apparently, I must convert .msh figure in an old version, but I have a
no idea how to do so.

Second, I understand how I must impose boundary condition and weak formula
within an homogeneous media. However, I don't know how to deal with
heterogeneous one?

Best regards
