help on the placement of the first node
 

Hi all,
I make a fine mesh on all the walls and use the enhanced wall treatment for my simulation. But in fluent manual of the enhanced wall treatment, it saies typically place the first near wall node at y plus around 1. what if my y plus are 0.5 or 0.7 which are smaller than 1, could anybody tell me if such finer mesh will cause prolbem for my simulation?

Thanks!

No, it will do fine, keep your y+ under 1.
