Dear Team,

 As per the above-highlighted image, we want to simulate the temperature distribution inside the confined bus terminal which has one entry and one exit point.

In this confined environment, we are defining different heat sources, like heat from condenser, heat from the engine compartment and heat from exhaust tailpipe.

In my simulation, the location of the bus is symmetrical from both entry/ exit surfaces and because of the heated source the hot air will leave the domain from both entry and exit surfaces and as well as the cool air from the ambient also come into the domain from the same entry and exit surfaces.

Therefore, is it appropriate to define the pressure inlet boundary conditions at both the entry/ exit surface because we don’t have any definite/ forced direction of airflow within the domain?

Thanks for your precious time.
