[CFX13]

Dear all,

I am trying to model the ideal gas law in CFX for the following model: The model consists of four walls with the same temperature and between the wall there is air (the ideal gas). The temperature of the walls is higher than the air temperature. We are using steady state computation. The gas is heated in the vicinity of the walls, therefore density and pressure vary. The density field, pressure field and temperature field have to match with the ideal gas law.

Up to now I get no proper results. Besides my setup, I also appended here the corresponding results I get in CFX. I suppose there are some errors in the boundry-conditions or I have an mistake in the setup. I would very much appreciate any advice regarding obvious mistakes or approaches to pinpoint the mistake.

Kind Regards
