Dear all,

I am newcomer in OpenFoam.

I would like to use mixed Smagorinsky model for an LES simulation of flows inside an car injector. This model seems to be efficient for my case study.

Unfortunately, I do not know how to set-up such model and my fvschemes produce the following error:

--> FOAM FATAL IO ERROR:
keyword div((dev((((surfaceSum((magSf*interpolate(sqr(U))) )|surfaceSum(magSf))-sqr((surfaceSum((magSf*interpolate(U)))|surfaceSum (magSf))))+(((0.666667)*((0.5*((surfaceSum((magSf* interpolate(magSqr(U))))|surfaceSum(magSf))-magSqr((surfaceSum((magSf*interpolate(U)))|surface Sum(magSf)))))+((((2*ck)|ce)*sqr(delta))*magSqr(de v(symm(grad(U)))))))-(nuSgs*twoSymm(grad(U))))))+(-nuEff*dev(twoSymm(grad(U)))))) is undefined in dictionary "/home/ubuntu/OpenFOAM/ubuntu-2.2.2/run/Kandi/putki/system/fvSchemes.divSchemes"

My divschemes is as follows:

divSchemes
{
default none;
div(phi,U) Gauss linear;
div((nuEff*dev(T(grad(U))))) Gauss linear;
div((nu*dev(T(grad(U))))) Gauss linear;
div((grad(U)&U)) Gauss linear;
div(phi,k) Gauss limitedLinear 1;
div(phi,B) Gauss limitedLinear 1;
div(B) Gauss linear;
}

I really need your shares... Please feel free to give comments and to suggest advices.

Thanks in advance,

vut

hi Vud

I am trying to run mixedsmagorinsk model at channel flow. But it gives me error. how did you solve the problem?

Best

RodriguezFatz will become famous soon enough
Just don't use "default none" but "default Gauss linear".
