Hi every body,

I want to define a equation as follows:



E parameter unite is m^2/s.

Is there such a parameter in CFX? or Is it possible to define such a parameter in CFX post?

Thanks.

The available variables are defined in the CFX documentation, in the reference guide. Density and Epsilon are available. I do not know what T_bar is so cannot say for that one.

Epsilon is available in CFX Post but with unit of m^2/s^2! i don't see unit m^2/s^3 in CFX post. I want to unit m^2/s^3!

Another question:

I want to define a parameter in unite of [kJ kg^-1 K^-1].

I think that i should define as follows:

[J kg^-1 K^-1]*10^-3

Am i right?

in the following post, urosgrivc stated that [J kg^-1 K^-1]*1000!! Why?

#6

because 1 kJ=1000 J!

Thanks

Opaque will become famous soon enough
What version of the software are you using ?

I checked on my installation, and for Turbulence Eddy Dissipation I get [ m^2 s^-3]

Are these ANSYS CFX results, or FLUENT results ?
