Plotting turbulentce length scale contour

Henry Arrigo · August 18, 2014, 07:19

Hi all
Is there any way that I can plot turbulence length scale contour in star-ccm+?
Thanks

If you use e.g. k-epsilon, you can calculate it from k and epsilon, see Modeling Physics > Modeling Turbulence and Transition > Using K-Epsilon Turbulence > K-Epsilon Turbulence Formulation > Boundary, Region, and Initial Conditions > Boundary, Region, and Initial Conditions

in rans models like k-e this is used as a way to specify the incoming and initial field turbulence and normally no value after that so i wonder why you would want to plot it due to the nature of rans models whereas with les you can see the large eddies of course
