Best regards

When the turbulence models are turned on, then FLOW3D applies the logarithmic wall function in the cells intersecting a surface. It assumes the center of the cells is with the turbulent region of the logarithmic velocity profile, which is approx: 30<y+<1000.

Lots of explanation in the user manual.
