Dear all ,

I have to solve the flow and heat transfer in microchannel heat exchanger consists of a number of channels rows for simplicty I solved the flow in only two channels and seperating wall .Now I would like to solve the flow in multi channels and walls but this is very difficult to plot it in gambit.

My question is .Is there are a method to duplicate the structure (two channels and seperating wall) and linke it together to make a heat ecxhager consists of multi channels.

Best regards rosol

Why would you need to do this. Would it be simpler to apply periodic boundaries within Fluent and solve it that way?

I guess that there are some limitations in termal boundary conditions for periodic problems
