Hi all,

I'm trying to simulate heat transfer on a finned tube heat exchanger. I have set a constant temperature condition on the tube walls.

My problem is setting a boundary condition for the fins. I want the heat transfer coefficient to be determined locally, based on the external flow conditions and the condition at the tube walls.

I have a feeling that what I'm looking for is a coupled heat transfer condition. Unfortunately this option is not showing in my thermal condition tab. Does anyone know how this problem should be treated?
