gonsanobre is on a distinguished road
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

snGradSchemes
