Hi everybody

i want to simulate film cooling in a blade simplified model with three rows of cooling holes at leading edge (three holes at leading edge and two at pressure and suction side).This is only a portion of blade. Actually, I solved the case without problems, but now the aim is to simulate all the blade, for this I want to put periodic boundary conditions in spanwise direction. I dont know how to put it for this case. For example, at plenum domain i need to select two faces to periodicity in spanwise direction, but one of this faces is the flow inlet, then this face will have two boundary conditions and is not possible. Also i have doubts how to do it in fluid and blade domain. I use Gambit and Fluent.

Can you help me? thanks in advance guys.

I attach a picture of the model
