Wall Function
 
Does Flow 3D have a wall functions? How does the phenomenon solve when y+>5?

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.

Can you please tell me in which version and section of the user manual it is explained about y plus and wall function in FLOW3D? I am unable to find
