The default model coefficients are

    {
    // Default kOmega Wilcox (1998) coefficients
        Cmu              0.09;

    }

For the revisited version of the model from Wilcox (2006), model coefficients should be modified following:

    twophasekOmegaSASCoeffs
    {
    // Default kOmega Wilcox (2006) coefficients
        betaOmega        0.0708;
        alphaKomega      0.6;
        Clim             0.875;
        sigmad           0.125
        popeCorrection   True (only for 3D cases)

    // Default SAS coefficients
        Cs          0.11;
        kappa       0.41;
        zeta2       3.51;
        sigmaPhi    2.0/3.0;
        C           2;

        // Delta must be specified for SAS e.g.
        delta cubeRootVol;

        cubeRootVolCoeffs
        {}
    }
