How is yplus calculated in OF?
Can someone offer some insight into what OF does when you calculate "yPlusRAS"? When I view the output "y" (distance from the wall) in Paraview, the numbers look right. When I plot "yplus", it seems to only give me one non-zero value at the node closest to the wall. Also, I can't seem to figure out how it exactly arrives at that number - does it use u_tau = sqrt(k)*C_mu^0.25 (where k is the turbulent kinetic energy)? If so, which value of k does it use? The value at the node nearest to the wall?
I apologize if this was posted elsewhere but I couldn't find any specific info on it and it was a bit unclear looking in the source code.
