How to calculate the Turbulence Itensity in LES
I am now using the fluent LES model to simulate a trasition problem. Can someone told me how to calculate the Turbulence Itensity and other parameters with the result that get from fluent LES model ? Now all these parameters is empty.

Fluent will calculate it for you. You can either view the data through contours, monitor through a surface monitor, or just go to report values for an average.

A quick note here:
By Default the method used for calculating the Turbulence Intensity in the panels is not accurate. This is already documented. Fluent uses a constant velocity as specified under Report -> Reference values. It is considered more instructive to use sqrt(2*k_phase/3) / |v_phase| in a custom field function and then obtain your Turbulence Intensity values from there. |
