Dyn Smagorinsky model in O.F. 2.1.x
 
Dear Buddies
Hi

I have seen in many threads that guys are working with dynamic smagorinsky model for SGS modeling in LES. However, when I tried Dyn Smagorinsky in O.F. 2.1.x got the following error:

Code:

Selecting LES turbulence model dynamicSmagorinsky


--> FOAM FATAL ERROR:
Unknown LESModel type dynamicSmagorinsky

Valid LESModel types:

6
(
DeardorffDiffStress
Smagorinsky
SpalartAllmaras
homogeneousDynOneEqEddy
lowReOneEqEddy
oneEqEddy
)


    From function LESModel::New(const volScalarField&, const volVectorField&, const surfaceScalarField&, const basicThermo&, const word&)
    in file LESModel/LESModel.C at line 140.

Would somebody PLZ hint me where the hell is Dynamic Smagorinsky?:confused::confused::(:(:eek::eek:

Hey bobi,
Did u figure out about the dynamicSmagorinsky model...? because i am stuck in the same situation at the moment..!!!!! :( :( :(

Hi
i have found a dynamic smagorinsky code from a guy that was written for incompressible solvers. reactingFoam and fireFoam solvers are both compressible. search forums ; you will find it.

you can find all the available models in:

OpenFOAM-2.1.x/src/turbulenceModels/incompressible/LES

and here you will find that the dynamic Smagorinsky was renamed to homogeneousDynSmagorinsky because the coefficient is averaged over the entire domain
