Yes, you're right: I've read back the theory and the range for viscous sublayer is y+<5. ;) Anyway if you use EWT, remember to go near 1 as much as possible. Regards

Because Enhanced Wall Treatment equations resolve the viscous sublayer of the Boundary Layer, where the non-dimensional distance (y+) is <1. y+<5 is anyway a good mesh but not optimal! If you want...

Hi Motorbean, k-omega SST required y+=1 in the boundary layer. I know that it's difficult to reach this target, so I think that y+<5 is anyway a good situation. k-omega SST uses Enhanced wall...
