is my Y-plus value allowed to drop below 30 at all
 

I am currently using fluent with the k-Omega turbulence model to simulate the flow over a naca0012 profile (2D) and my Y-plus drops below 30 in some sections of my Y-plus plot. my question is this every acceptable for accurate results of can my Y-plus value never enter the region of 5<Y+<30?
I have attatched a picture of the plot

Get your yplus to be around 1 or slightly lesser and the community will take your results more seriously. That is if you're not using wall functions
