Abstract
The European 6th-framework project VIRTUE aims at advancing the use of CFD in ship design. Workpackage 1 of this project considers the prediction of steady flow around the hull, resistance and propulsion; the field in which the use of CFD is most widespread. Several CFD codes are able to predict the viscous flow and wake field accurately today. However, the predicted resistance and its components are often not so accurate.
The present paper reports ongoing work in which studies are done for viscous flow computations including free-surface effects. Computations show that both for model and full scale the estimated wave resistance is very small and the numerical accuracy is still insufficient to predict it for the present tanker case.
