Convection over an enclosure

      I am trying to simulate convection heat transfer from an enclosure. only top and bottom faces are exposed to the environment while the sides are coated with silicon. Can you please tell me how should i create the boundaries. 


      Should I only assign upper and bottom faces as boundaries as only these two are exposed to environment?

      How does the geometry look? Insert a small sketch of the problem.

      This highlighted face and the bottom flat face are exposed to the environment. Rest of the geometry is coated with silicon.

      I tried assigning these two faces as sink_walls but fluent is not allowing me to use coupled boundary conditions on these. When I checked in the user manual it says coupled boundary condition can only be applied on faces that form the interface between solid and fluid.

      I assume you have several solid bodies which can be read into Fluent + the gaseous enclosure if you want to run a complete CHT in Fluent.
