Hi everyone, I'm calculating resistance of a submerged body using StarCCM

my Y+ values are ranging from 0-12 along the length of the body. I'm using K-epsilon turbulence model still, is something wrong I'm doing here ?

please let me know

Generally you want you 1 (low Y+) < Y+ > 30 (High Y+)

Are you using Prism Layers? If you are aiming for Low Y+ you should try and reduce the size of the near wall cell.
