Hello,

I have a problem in making the periodic BC in 2 directions.

In my problem, x direction is the streamwise direction,
and i want to apply the periodic BCs in y and z directions.
It is very similar to the case of a turbulent channel flow.

To this end, I generate surface mesh (using Fluent meshing)
and then make an option of 'Set up periodic boundaries (right click after doing 'generate the surface mesh')'.
At this stage, I can make one periodic BC in y direction,
but i don't know how to make additional periodic BC (in z direction).

I would appreciate it if you could answer my question.

Best regards,
