Hello everyone, I'm new to CFD and I really need some help.

I am simulating a data center model. I want to set the boundary conditions of Heat Flux on the surface of the server. In order to simplify my problem, the attached file is a schematic diagram of my problem. How can I make the intersecting surface be heated and allow airflow to pass through at the same time?

You will want to define the interface as a Radiator. Use "Share Topology" in spaceclaim or DM and name the face in meshing something like "HeatedFace". In fluent, the face should be read as "Internal". Right click on the face and set it to radiator.

In the radiator dialogue box you can set either a heat transfer coefficient and temperature, or a heat flux as W/m^2. If you want to use the heat flux make sure you set the temperature to absolute zero. See attached picture for further details.
