May 26, 2022 at 10:20 pmYrnasoSubscriberI'm looking to obtain a single Y Plus value. I've seen suggestions to use XY plots or histograms, but those give me a range of values instead of one "overall" value. Is there a way to do this?
May 27, 2022 at 9:04 amNikhil NaraleAnsys EmployeeHello,
The y+ value is calculated for every cell on the wall. Which means it will keep on varying throughout the domain. As per my opinion, a single value of the y+ will not give a correct picture.
However, if your aim is to keep the y+ below a particular value (let say 1 or 5), then it makes sense to monitor max y+ value in the domain.
May 27, 2022 at 10:22 pmYrnasoSubscriberI see, thanks for correcting me. So the max Y+ is more relevant than the "average" Y+? For example, if I wanted to be as close to a Y+ of 1 as possible would this plot, which has a majority of points near 1 but peaks at 3.3, be less preferable to a plot that peaks at 1 but has most of its points below that?

Ideally, it is. With that said, it is not always possible to maintain y+ max within the recommended value. At least make sure that y+ values in the important and critical areas are satisfying your criteria.
For example, if I wanted to be as close to a Y+ of 1 as possible would this plot, which has a majority of points near 1 but peaks at 3.3, be less preferable to a plot that peaks at 1 but has most of its points below that?
I think, the above answer will suffice.
