Where to measure y+
Where should I calculate/report my y+ in for instance a backward-facing step flow, where the friction velocity (and thus y+) varies greatly throughout the domain due to boundary layer separation, reattachment and recovery. In the literature, people always report one single y+, but is this for instance taken at a specific point in the domain, is it the single highest y+ along the given wall, or maybe an average?
Thanks for any help!
