I'm trying to do a similiar simulation (using interMixingFoam) with model LES and RAS, on setting RAS simulation i did some changes on the files:
-including the nuTilda file and epsilon file -changed turbulence properties from LES to RAS -changed some boundary conditions. After simulating it detects some errors like : -no MRF models present (i think is optional, i'm i wrong?) -GAMG: solving for pcorr, initial residual=0 , final residual=0, No iterations 0 time step continuity errors: sum local=0, global =0, cumulative=0 -mpirun detected that one or more processes exited with non-zero status, thus causing the job to be terminated. the first process to do so was: Process name :[[46642,1],0] exit code : 144 (where can i find this process?) i searched a lot about fvSchemes to try finding the error on fvSchemes but i dont know where do i have to change the code. I'm thankfull if you give me some tips please here's my fvSchemes ----------- FoamFile { version 2.0; format ascii; class dictionary; location "system"; object fvSchemes; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // ddtSchemes { default Euler; } gradSchemes { default Gauss linear; } divSchemes { div(rhoPhi,U) Gauss limitedLinearV 1; div(phi,alpha) Gauss vanLeer; div(phirb,alpha) Gauss linear; div(phi,k) Gauss upwind; div(phi,epsilon) Gauss upwind; div(((rho*nuEff)*dev2(T(grad(U))))) Gauss linear; } laplacianSchemes { default Gauss linear corrected; } interpolationSchemes { default linear; } snGradSchemes { default corrected; } // ************************************************** *********************** // |
