CFX Documentation
Hi all,

Whilst I've been using CFX I've come across a lot of people talking about rules to do with y+ values for the k-epsilon and k-omega turbulence models (y+>10 for wall function in k-epsilon, y+>20 for k-omega etc.). I've always used this where appropriate and that's fine.

However for the first time I've actually had to find a quotable source for a write-up to justify the use of this. The most recent reference to this I can find in CFX documentation is from CFX 5.5.1, I'm now using ANSYS 14.5 and the equivalent part of the documentation seems to have been stripped of these helpful few lines.

I was wondering if anyone was aware of when or why they took this out of the documentation and of other sources which I may be able to use.

Many thanks,
