[Nek5000-users] Periodic-AUTO using pretex problem

[nek5000-users at lists.mcs.anl.gov]

Hello Neks, 

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. 

But its running for a long time. It means its running through the same elements again and again. 

I tired on a simple case (example a cube). it worked well. 

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. 

So could you please tell me how can I solve this problem? 

Thanks in advance
