Input heat source (heat/unit volume) in 2D

March 17, 2005, 03:47

Dear all

I'm simulating the 2D free convection flow in a building and I want to set the heat source (heat per unit volume) in attic. Can I do that? (I find the unit of energy source is in W/m^3).

I try to do that but it's answer is divergence in temperature.

Please give some suggestions about this problem if you know. Thanks before.

Hi Polly

I believe the third dimension that is used for 2D simulations is the Depth value set in the reference values (default = 1m).

Hope this helps

Dear Mark

Thank you for your suggestion and I have the next questions. I ever used a unit depth in z-diection in CFX-program but never use with Fluent program. This your suggestion, your mean it's can use for Fluent program?

Thank you.
