    Hi Adityan,

    Good improvement.

    we should think carefully in OpenFOAM. We said to OpenFOAM so far that we would like to use komegaSST model. then specified missing Omega file in /0 folder. But we didnt say to OpenFOAM that how omega equation will be discretised?

    therefore please add below line in the fvScehemes files of divSchemes section

    div(phi,omega) Gauss linearUpwind grad(U);

    and then you should also tell OpenFOAM how the omega matrix will be solved.

    therefore you should also add below lines inside fvSolution file under the solver section,

    “(U|k|omega)”
    {
    solver smoothSolver;
    smoother symGaussSeidel;
    tolerance 1e-06;
    relTol 0.1;
    }

    “(U|k|omega)Final”
    {
    $U;
    tolerance 1e-06;
    relTol 0;
    }
    I hope that it clarifies your questions

    Best.

    Barış
