A full numerical simulation of wave dynamics at coastal structures with the volume of fluid method

The volume of fluid method (VOF) of Hirt and Nichols(1) is applied in the simulation of transient waves at coastal structures where the fluid free surface gets mostly distorted at impact zone and important wave interactions with external boundaries take place(2). The numerical stability of a VOF based code is maintained during the simulation of five wave periods which are generated by a weakly reflective boundary condition (WRIB). In this paper, the VOF method is not fully introduced but numerical techniques for solving the Poisson equations at arbitrary boundaries are discussed with cases of wave flows in a 35.m long and 1.5m deep pool with a slope are shown.
