Abstract
A fully-implicit multigrid method has been developed for the computation of time dependent free surface flow. The method uses the generalized artificial compressibility approach to couple the incompressible Euler equations and continuity equation in a hyperbolic manner which allows several techniques for convergence acceleration to be implemented. Two grid adaption strategies are used to capture wave motions as well as wavemaker's oscillations. Comparisons are made between these two techniques and experimental data of the flow field around a NACA 0012 airfoil placed beneath an initially calm free surface. Transient solutions of a wave-maker oscillating horizontally are also presented to validate the new method.
