Heat flux
 
Hello!
Please, help me!

How to set heat flux in Star-CD?

Please write if you have any ideas.

Thanks Pauli!

Now I need to set heat flux in [W/m3] or loads in [W].

Please write if you have any ideas.

RTM

3. Flux (constant) wall heat flux value [W/m2]

There is a 3D model in which through a solid heat flux is passed. A body unevenly cools down a liquid, that condition uneven heat flux from all surfaces. I must count up distributing of temperatures in models and wall heat flux coefficient. For this purpose it is necessary to set a by volume heat flux for a solid [Вт/м3].

Help please, what method it is possible by to set him?
Found only how to set a superficial thermal stream [Вт/м2], but for set the problem he will not give a necessary result.

Please write if you have any ideas.
If something is needed to specify, ask, I will tell.

Sounds like you want to specify a volume source. If so, you can use the command rsource or the user subroutine sorent.
