Problems calculating y and y+ after processing

manu551 · January 7, 2017, 06:47

Hi all,

1. I tried to calculate y+ after processing my case (a circular cylinder at Re = 30470) with pisoFoam (SpalartAllmaras) using yPlusRAS utility and it works, but yPlus is always (everywhere and every time step) 0

How is it possible?
2. Do you know any utility to calculate a dimensioned distance "y", "ds" or "delta_s" which described boundary layer thickness?

Thanks.
