    Hi Adityan,

    Standard kOmega models are mainly used for near-wall treatment. (kOmega)-SST stands for shear stress transport. The SST formulation switches to a k−ϵ behavior in the free-stream, which avoids the k−ω problem of being sensitive to the inlet free-stream turbulence properties. However, it is used wallDistance treatment in the boundary layer.

    Therefore, you should define wallDist model in system/fvSchemes to let openfoam how to calculate it.

    Please add below lines end of fvSchemes file and then run again

    wallDist
    {
    method meshWave;
    }

    It will work.

    Best.

    Barış
