You also need to account for how you're working near the walls: ie wall function or fully resolved viscous sub layer. Roughly the values are 30 < y+ < 300 or y+ = 1 (ish) respectively. Read the help guides (mainly theory) for more information on what values you need and when you should use which approach.
