Hi all.

I have got a question on the SA-DES model. In most of the references, the DES model is defined by replacing the distance-to-wall $d$ by the grid length scale $\tilde{d}$. However, in several papers only in the destruction term $d$ is replaced and in the rest equations using $d$, such as the definitions of $r$ and $\tilde{S}$ (SA model here: http://www.cfd-online.com/Wiki/Spalart-Allmaras_model), nothing changed. I would like to know which one is correct, or more precisely, which one is the original formulation in the DES97 paper? Sorry I do not have the DES97 paper at hand.

Cheers.
