How to define the Y plus value?
 

Hi, How to define the Y plus valuse when using the turbulence model? For example: flow around a cylinder, what's the relationship of the near wall grid hight and the Y plus valuse at the air conditions? I'm confused with this.

who can help me?

Thanks.

see help, section 11.10--Grid Considerations for Turbulent Flow Simulations, here, assuming ur version is Fluent6.2.16.
