S-A y+ problem
 
Dear all

I know that if I am using a k-epsilon model with near wall treatment as two-layer zonal then my y+ must be below 4 or 5. What is the y+ value that lets the S-A model work probably, I have been told that it should be between 50 and 60, is this true?

Cheers

Andy

Silly question maybe, but what is the S-A model?

It is the Spalart-Allmaras turbulence model that can be used in Fluent, and can be found in the define menu. I would have thought that if you where using fluent you should have spotted this.
