Dear all

I am doing flow simulation analysis of a server rack. A Rack have 15 server nodes in it. Each server node is having 4 fans inside, which will suck the cold air from the front side of the rack, and this will be blown out from the back side of rack. The cold air will absorb heat inside server while taking this trajectory.

I have designed all the 17 nodes as a block. 17 extruded cut represents the number of server nodes. 2 Internal fans are assigned for each server nodes. The screen shot is attached for your reference.

In my model it seems to have 34 fans inside and i have assigned 30 internal fans. Assigning each fan inlet and outlet seems to be a tiresome job. 

I need to expand my simulation to more number of server racks. Then it will be even worse. Kindly suggest whether i am on correct track. If not kindly suggest me a better solution
