The default model coefficients are
twophasekOmegaCoeffs { Cmu 0.09; alphaOmega 0.52; betaOmega 0.072; C3om 0.35; C4om 1.0; KE2 1.0; KE4 1.0; alphaKomega 0.5; alphaOmegaOmega 0.5; Clim 0.0; sigmad 0.0 popeCorrection false; }
For the revisited version of the model from Wilcox (2006), model coefficients should be modified following:
twophasekOmegaCoeffs { betaOmega 0.0708; alphaKomega 0.6; Clim 0.875; sigmad 0.125 popeCorrection True (only for 3D cases); }
