Dear Frends

I want to enable the low reynolds number version of SST model. How to do this? I can only see the automatic wall treatment in the CFX pre.

Best Regards
Far

There is no Low Re version of SST. It does not need it as the k-omega based turbulence model works reasonably well at low Re with no modifications.

Dear Ghorrocks,

I want to run the standard SST model without automatic wall treatment. The standard SST has the requirement of yplus less than 2 (as on the K omega model)

Do a search in the CFX help file and you will find a lot more information about the SST model and wall functions.
