In this paper, some recent progress toward the prediction of fully coupled wave-body interactions using a sharp interface immersed-boundary/level-set method is presented. A non-iterative strong coupling scheme for the fluid motion and rigid body dynamics is adopted by utilizing a non-inertial reference frame attached to the solid body. The combination of this scheme with the previous immersed-boundary/level-set method gives a robust and efficient tool for the prediction of solid body motions in waves. Several examples are presented to demonstrate the applicability of the new method. Possible further developments are discussed.
