I have a computer in a room. The computer has surface temperature of 38 degree C and the heat generated inside the computer is 1000 w/m3. The problem is that when I make the geometry and input it in the cfx, there is a interface created between the computer wall and room air. Thus, not allowing me to put temperature B.C. at the computer surface which acts as a interface. Similarly if i convert the interface into the wall and give my B.C then the effect of convection is not seen, basically the two domains don't interact at all. How can i solve this problem? Please Help.
