How to plot u+ Vs Y+ graph?
 

I want to plot a graph between u+ and Y+. I m not able to get a plot, can anyone help me out in this..

The same question....please!

What I usually do is to plot velocity as a function of wall distance (define a line probe to get the plot) and export it to excel, and use excel to non-dimensionalize the plot to get u+ vs y+. You will need the shear stress at the wall though, and you can get it by a point probe, or just using the line probe that you have and plotting the wall shear stress on that line. You will get a single value at the wall and zeros every where else.

I don't know if this answered your question or not.

what else do you do from there? I did what you said so far but am not getting the correct plot.....

What do you get when you follow the steps? Can you give a little bit more detail? I haven't done this for a while now, so can't remember exactly if there were any tricks or something to watch for.
