Hello all,

I want to know what is the difference bet. standard wall functions and enhanced wall treatment.
Also for standard wall functions y+ if the minimum is less than 30 is that wrong? and how could i adjust its value , i use the adaption but the min always less than 30 ?

thanks in advance.

wall function

Enhanced wall treatment in Fluent is equivalent to automatic wall treatment in CFX (roughly speaking)

use the yplus calculator available online and is based on flat plate formulae. It is a good starting point, later on you can fine tune yplus once you have simulation results (you should get idea within 25-40 iterations). http://geolab.larc.nasa.gov/APPS/YPlus/
