sarav New Member Join Date: Jul 2009 Posts: 25 Rep Power: 16	Hi I'm testing the transition model gammaRetheta in star-ccm+. I would know how I can identify the point at which transition starts. I could use: -a plot of skin friction coefficient -a plot of tubolence intensity -a plot of eddy viscosity -other (tell me ) What do you think it's the best choice? The main problem is that using skin friction coefficient the transition starting point is not very evident; instaed if I use a plot with intensity I get a transition point which is different from the one I get using a plot with eddy viscosity! Thanks!
