You should explain what you are trying to do, that is what you should do.
Please show an image showing the non-periodicity, and another image showing your geometry and boundary conditions. Also include your output file.

Hello.
I am not sure but it looks like You are talking about interface between rotational and stationary domains. For steady state simulation use Frozen Rotor instead of Stage interface. Best regards, Oskar |
