mantec is on a distinguished road
I am working on the implementation of the wall function for my code.

I found out the y plus and u plus values at the nodes next to the wall. What should i do after that.

if y+ < 11 y+=u+ and if y+ > 11 some log function.

What to do after finding out y+ and u + values

1. do i need to find the velocity u from u+ (u/Ut) and replace this velocity with the old velocity at the nodes next to wall

2. Find the viscous shear stress using the velocity from u+

or there any other ways to implement the wall function to the code.
