In the following expression -

((T/273[K]))^(1.81)*(101330[Pa]/Pref )*2.305e-5[m^2 s^-1]

What kind of averaging is applied in CFX (CFD Post) to the temperature(T), i.e.., is it mass averaged or volume averaged or any other averaging is applied.

Could some one please explain this.

Are you calculating this function on the nodal values or over some form of average over a mesh object?

Hi Glenn,

No I did not average it over any object, I'm evaluating it just the way it is I mean it is evaluated as itself and not by passing it as an argument to some averaging function

Then it is calculated directly on the nodal values with no averaging, and returns a value at each node. Or are you asking what is the basis of the nodal values of temperature?

Thanks for the clarification Glenn, No im not asking about the basis, like i know that the nodal values are just a part of the solution and your reply clarified my question.
