Hi,

I have a question to the new Version of the Spalart-Allmaras turbulence model.

1. What is the advantage to use
...
+ fvm::div(phi_, nuTilda_)
- fvm::Sp(fvc::div(phi_), nuTilda_)
...
(means phi_ grad nuTilda_) rather than
...
+ fvm::div(phi_, nuTilda_)
...
in the nuTilda equation.

2. What is is the advantage of the new implementation? I wasn't able to find this formulation somewhere. Is it still a kind of a "Low-RE" model.

Andreas
