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 |

Just don't use "default none" but "default Gauss linear".
