       Hello,


      Moving this post to the Fluids thread.


      This depends on which near-wall model you are using. If you are using the standard wall function, y+ ~ 30 should be good. Enhanced wall treatment will require y+ ~ 1 or lower. 


      Hope this helps.


      Best,
      Karthik

      For Wall Boiling using RPI based approach please use Near Wall Mesh with Yplus larger than 30-40.
