Hello,

It is explained in the following COMSOL Blog article: https://www.comsol.com/blogs/which-turbulence-model-should-choose-cfd-application/ (see the "Wall Function" paragraph)

Please find some updates (in 5.3a) in the following COMSOL Blog article: https://www.comsol.com/blogs/why-should-i-use-automatic-wall-treatment-for-my-cfd-modeling/

I hope this helps !
