Here is an updated compressible dynamic smagorinsky LES model with the inclusion of a SGS K equation solved by feeding the locally dynamic muSgs coefficient into the K equation.
This code was utilized for OpenFOAM 1.7, and it needs to be slightly modified for OpenFOAM 2.1. Cheers, Deji

Thanks a lot. We implemented your old version in OpenFOAM 2.1 and it works great. We would surely modify it and use this new version. I undertand that this is exactly the same at the previous 'dynLocalAverageSmagorinsky' except for the change you specified. Is there something else that's new in this new version !
Thanks again for all the help. Sagnik

Dear Deji,
Could you please also nicely share us the Make folder (files and options) for the dynamic Smag Model: dynLocalAverageSmagorinsky.C Thank you so much! flames

Hello, everyone!
I tried to complied the dynLocalAverageSmagorinsky Model into openfoam 2.1.1. But I still met some problem when I run my case. I put the .H and .C in the following path: Code:

Dear Deji,
In the source code of dynLocalAverageSmagorinsky.C, the resolved turbulent stresses L_ij is calculated as: Code:
volSymmTensorField Lij = filter_(rho()*sqr(U()))  sqr(filter_(rho()*U()))/filter_(rho()); Did you test this assumption? I know that in compressible L_ij is easy to calculate in compressible LES, but as you know in openfoam it is not actually compressible. At least in my case it is Low Ma solver. I ask this just for curiosity. Thanks. Last edited by flames; February 9, 2014 at 11:36.

Since it seems you are interested in more sophisticated SGS models, please have a look at the LEMOS extensions for OpenFOAM: Dynamic Mixed Model, Lagrangian Dynamic Mixed Model and Hybrid URANSLES models with dynamic Smagorinsky :)

Thank you for your information. Are they for compressible or incompressible LES?

Dear Deji,
About the calculating the dynamic parameters Cd and Ci for the Smagorinksy compressible LES SGS model, I think I have the following difference for my implementation: First CI, the beta should be calculated as: Code:
volScalarField beta = 2*sqr(2*delta())*filter_(rho())*sqr(mag(filter_(rho()*D)/filter_(rho()))); thank you so much! For clearance, I post the function I am using to predict Cd and Ci: Code:
volScalarField dynLocalAverageSmagorinsky::cD_(const volSymmTensorField& D) const { volSymmTensorField Dfilter = filter_(rho()*D)/filter_(rho()); volScalarField magSijfilter = sqrt(2.0*(Dfilter && Dfilter)); volScalarField magSij = sqrt(2*(D && D)); volSymmTensorField Lij = filter_(rho()*sqr(U()))  sqr(filter_(rho()*U()))/filter_(rho()); // volSymmTensorField Bij = 2*sqr(2*delta())*filter_(rho())*filter_(magSij)*(filter_(D)filter_(tr(D))*I/3); // volSymmTensorField Bij = 2*sqr(2*delta())*filter_(rho())*magSijfilter*(Dfilter  Dtrfilter*I/3); volSymmTensorField Bij = 2*sqr(2*delta())*filter_(rho())*magSijfilter*dev(Dfilter); volSymmTensorField Aij = 2*sqr(delta())*rho()*magSij*dev(D); volSymmTensorField Mij = Bij  filter_(Aij); volScalarField LijMij = Lij && Mij; volScalarField MklMkl = Mij && Mij; // Performing local average on cell faces on return return fvc::average(LijMij)/fvc::average(MklMkl); } Code:
volScalarField dynLocalAverageSmagorinsky::cI_(const volSymmTensorField& D) const { volSymmTensorField Dfilter = filter_(rho()*D)/filter_(rho()); volScalarField magSij = sqrt(2.0*(Dfilter && Dfilter)); volSymmTensorField Lij = filter_(rho()*sqr(U()))  sqr(filter_(rho()*U()))/filter_(rho()); volScalarField Lkk = tr(Lij); volScalarField beta = 2*sqr(2*delta())*filter_(rho())*sqr(magSij); volScalarField alpha = filter_(2*rho()*sqr(delta())*sqr(magSij)); // Performing local average on cell faces on return return (fvc::average(Lkk))/(fvc::average(beta  alpha)); } Quote:

Dear All,
In dynLocalAverageSmagorinsky and other dynamic LES model, when we need to calculate the model constants using a dynamic way, we will do the averaging, like i.e. <Lij*Mij>/<Mkl*Mkl>. In principle, this kind of averaging is performed in the homogeneous direction in the flows. I do not know how this is implemented in other flow solvers. In openfoam, this is done using fvc::average(), this operation is only based on weighting of areas of all the faces belonging to one cell. So this is LOCAL dynamic method. Could anyone say something about if such implementation is really reflecting the averaging in the original sense (i.e. averaging in one homogeneous direction)? OFFO Thank you

Hi All,
When I use this dynamic model, for the regions having large mesh size, I found there are negative muSGS appearing there. So I cannot confirm if this is acceptable results or not. The flow fields and pressure seem still fine even if the mySGS is negative there. Anybody has such kind of experience using dynamic Smagorinsky model? OFFO

i compiled it with 2.3.x and it works well.
but you need to modify some small parts. just diff the comp. Smagorinsky from 1.6 or 1.7 with the actual one. Thats all.
