<div>Hello Neks,<br>
</div>
<div><br>
</div>
<div>I was setting up a mesh of NACA foil in 3D with periodic BC on both sides. Since there was some problem with converting BC's from ICEM to NEK5000. I gave a space as BC and then using prex I fill up the empy spaces by using periodic Auto button.</div>
<div><br>
</div>
<div>But its running for a long time. It means its running through the same elements again and again.<br>
</div>
<div><br>
</div>
<div>I tired on a simple case (example a cube). it worked well.<br>
</div>
<div><br>
</div>
<div>The difference between the NACA case and cube is that, along the spanwise direction of NACA I did not give any elements (i just give a thickness to the mesh) but for the cube there were 2 elements in Z direction.<br>
</div>
<div><br>
</div>
<div>So could you please tell me how can I solve this problem?<br>
</div>
<div><br>
</div>
<div>Thanks in advance<br>
</div>
