BC when using nutUWallFunction
 

Hallo foamers,
i am trying to simulate an impinging jet with different turbulence modells.
While experimenting with the k-epsilon modell i figured out, that it is designed for high-Re simulations and walls have to be treated seperatly by wallfunctions.

Currently i am confused about the use of the different Wallfunctions for nut.
According to the tutorials i set kqRWallFunctions for k and epsilonWallFunction for epsilon when using nutkWallFunction.

Can someone explain me the difference between the different nutWallFunctions and give a hint accordning the BC of k and epsilon?
