Icem 2d meshing for multi-element airfoil
 

I'm now trying to make 2D mesh for airfoil.
When trying with single element airfoil, I can mesh in the way of Simon's video.

But, now I'm trying to multi element airfoil.
Making grid take me long time for multi element, so I'd like to mesh with"compute mesh".

I make surface at fluid area, and cut the inner of airfoil.
(There is no surface inner of airfoil)
And then, compute mesh, i can see mesh corectlly.

But after output to fluent v6, can't read the mesh with notice"fatal error"

Please tell me what is the problem and what to do.

Thank you.
