[Nek5000-users] Periodic-AUTO using pretex problem

Dear Sijo,


I would recommend using n2to3 to extrude

the 2D geometry

and then periodicity will be built in.

Subject: [Nek5000-users] Periodic-AUTO using pretex problem

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

Sijo GEORGE
