tutorial of non-newtonian transitional flow in an eccentric annulus
 
I am doing one tutorial of fluent the title is "Non-Newtonian Transitional Flow in an Eccentric Annulus". I have define inner and outer as a wall in gambit but I when I define the periodic I don't know how to do it because I can not export it.
gambit give me this error (ERROR: Periodic Boundary Entities are not specified correctly. the two periodic entities must be link meshed and specified on the same boundary entity).
can someone help me?
thank you

Non-newtonian tutorial
 
I am doing the same tutorial as you, and I have the same problem.
If I get any solution I will tell you how I did it.

For this you must link the two faces. It is first icon from left in the second row of face mesh.

Thank you very much, I have linked the two faces
I get the mesh but I can not make the same mesh as in the tutorial, if I use Hex for mesh it gives me error, I use the tet/hibrid mesh. I mesh the volume automatically is it right?

Thank you
