How to set a non-zero pressure

      Hi there,


      I was wondering if you could help me by letting me know how to set the operating pressure for a not-sea level location in the setup page.


      My model is a "thermal wall" prototype made with a wooden frame that is not airtight, so air can leak in and out as the temperature changes so that the air pressure in the prototype will not change.


      Also, I was wondering if you can give me any suggestion to model two panes of glass, the air cavity between them and a partial solid insulator that is also between the glass. In the CFD model, the walls are rigid, so as the temperature rises in an ideal gas, the pressure would go up, but in the experimental prototype, the pressure doesn't go up.


       


      How can the CFD model accommodate the fact that the pressure will not actually change? Does that change the need for a coupled solver? If yes, please let me know how to do it. 


      Sincerely,
