Hi everyone,


I would like to start a Simulation that contains slip walls and a turbulence model (kOmegaSST). I am not sure about the BCs when I use slip walls in U.


Is it right to keep:


k: kqRWallFunction

omega: omegaWallFunction

nut: nutkWallFunction

alphat: alphatWallFunction


or should I rather apply a zeroGradient BC? As far as I understood, the kqRWallFunction wall function is basically a zeroGradient BC.


Thanks in advance!
