<p>Good morning,</p>
<p>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)</p>
<p>I use the plugin crack to define two different boundary condition for each side of the same surface.</p>
<p>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.</p>
<p>I don't understand why it doesn't work for this geometry.</p>
<p>Do i use a crack plugin badly?</p>
<p>Can you say to me what i did wrong?</p>
<p>You can find in this link the geometry in geo, msh and bdf format and the script for the crack plugin:</p>

<p>The surface that are divided in two, are the surface with groupphysique number : 4,7,37 and 5.</p>
<p>And i don't understand why only these four surface are wrong, while the other are right in Ansys CFX</p>
<p>thank you</p>
