Boundary condition w/o wall function
 

how can i set the boundaryfield in 0 folder(nut, omega, k) , if i don't want to use wall function for several boundaries???

I'm using kwsst model and It seems that k, nut, omega field might be changed respectively in different ways .

did you try fixed value with a value of 1e-18 or another low value, or even 0 at those boundaries?
