Koranten New Member Join Date: Jul 2009 Posts: 14 Rep Power: 17	Hi! In FLUENT, is it possible to create a lumped mass of air? I mean, I have equipments being heated from the inside and they are cooled by outside air. I would like to model this air by a simple mass of air, I would like to avoid solving the Navier-Stokes equation for this air volume. To do so, I would just set a convection coefficient, but of course the temperature of the air will rise. Is there a way to do so? I could make a UDF to define the outside air temperature, but this air is heated by many equipments, meaning many different surfaces. Is it possible to get the heat flux from several surface boundaries at the same time? Thanks.
