Boundary condition in fluent
 
Hello
I am a new user in fluent

How can the change in flow direction affect the periodicity of the flow ?.

This option can be accessed from Boundary condition ==> Periodic Conditions

The manual said :
Flow Direction
sets the direction of the periodic flow. The direction vector must be parallel to the periodic translation direction or its opposite.

but it is not clear to me

Thanks in advance
