during the post processing, under variables, i saw that my solver yplus value is [ min 0 max 66789] and yplus (min 0 max 38079). Do these values mean that my yplus values are too high? I need at least below 100 yplus value.

You cannot assess accuracy on y+ alone. You need to do a mesh sensitivity check.
But y+=38000 is pretty huge and is definitely far too big. You will definitely need a finer mesh than that. |
