Periodic boundary for heat exchanger
 
Hi,

I'm new to cfd as I'm learning it for my thesis, so I'll apologize in advance for my rather rudementary question :)

I'm trying to model a louver-finned heat exchanger and I got a bit stuck at the boundary conditions of the top and bottem interface:
I want them to be periodic (flowing out of the top = flowing in at the bottem)

Now i got this to work using the text commands in fluent using:
"mesh/modify-zones/make-periodic/"
However, this means that every time I alter my mesh / update my project using the workbench, I have to redo these steps

So my question is:
How do u define periodic boundary (translation) in ansys mesher, so that I don't have to redo the modifying of the zones every time.

So far I've tried:
Adding match control and making the faces into 1 named section called 'periodic'
