Re: Best Way to Capture Boundary Layer Thickness
 
I don't know if I got your question right...but I assume you need to properly calculate your Ywall (height of first cell) based on the deisred Y+. Rule of thumb: 9-15 cells should be within your boundary layer in order to have good representation.

You can check your result by checking the contour plots of Y+ distribution and addapting your grid accordingly.
