Abstract
A vortex tracking method is used to study forced harmonic roll motion of a two-dimensional floating body with sharp corners. The effect of free surface waves is incorporated. Errors due to numerical and physical problems are discussed. The presented test cases show that free surface waves have an effect on the vortex generation, whereas the free shear layers do not have a noticeable influence on the free surface waves. The results show that roll damping due to eddymaking and wave generation cannot be separated.
