I was dealing with a electronics cooling problem and I had power sources to be considered for simulation. The info. available being the output power and the service temperature range for the power sources from the specification manuals.

So in general while in such simulations is it fine to just go with the out put power ( in W) (or) will it also be required to take into account the info. about the service temperatures.
If so how do we account for the service temperatures in CFX

What are you trying to achieve with your models? CFD is merely a computer experiment, you just give it a set up and it tries to predict what the flow would look like given that set up. It does not give you the "answer", as many seem to believe.

What you do with the service temperatures is up to you. But for CFD you need to consider scenarios - "What would happen if the ambient temperature was 50C" or "What would happen if the cooling fan stopped"... these are scenarios where CFD can give you predictions of what would happen.

Many thanks for the clarification Glenn.
