Dear Friends,

I am using a Smagorinsky LES model in my simulations but I can't make a contour plot of the turbulence intensity since that option does not exist in the contours list. I have to make a user defined function but don't know how the turbulent intensity is defined in fluent for this turbulent model.

I have used the equation TI = u'/u

where u'=( 1/3 * (uv'^2 + uw'^2 +vx'^2) )

where the terms uv', uw' etc are the resolved reynolds stress components obtained under unsteady statistics. But this does not give reasonable contour plots.

Can anyone please help me to define the turbulent intensity.
