Good morning,

I used GMSH to make geometry and next to export it in Ansys CFX with a bdf 
format ( the only one that work, that last time i tried)

I use the plugin crack to define two different boundary condition for each side 
of the same surface.

Until now, this methode work very well. But lastly i built a more complexe 
geometry, and the exportation in bdf format give surface divided in two pieces.

I don't understand why it doesn't work for this geometry.

Do i use a crack plugin badly?

Can you say to me what i did wrong?

You can find in this link the geometry in geo, msh and bdf format and the 
script for the crack plugin:

The surface that are divided in two, are the surface with groupphysique number 
: 4,7,37 and 5.

And i don't understand why only these four surface are wrong, while the other 
are right in Ansys CFX

thank you

Adrien
