periodic channel flow
 

I know there have been similar topics in the past, but I would like to be absolutely sure that I'm doing everything correctly. I'm not normally using starccm+, the reason I'm using it now is to validate some results. None of my colleagues can help me so:

I want to run a periodic channel flow (incompressible) with heat transfer (passive scalar transport).
(so I want a fully developed flow in a channel). I have a wall with constant heat flux.
1. I define inlet and outlet as periodic
2. Set inlet to velocity inlet, outlet to flow-split outlet
3. In interface boundary, I select fully developed interface boundary
4. in fully developed energy option I select constant heat flux walls
5. for flow I select mass flow rate
6. I specify bulk inlet temperature.

So my question is: is this procedure correct? I read the manual, but I wasn't able to find an answer on this question inside.

Thank you very much for reading,
