Hi,

I`m using Star-CCM in order to predict the drag of a vessel. Pressure Forces are predicted (assuming a 5% error) correctly but Shear Forces are too low.

Obviously I run turbulent flow with RANS turbulence models, specifically k-epsilon two equations model (the Realizable one).

Does anybody know what parameters of the corresponding turbulence model have to be changed for increasing the shear forces?

Thanks a lot.
