Abstract

We present a numerical three-dimensional time-domain method which is used to study the nonlinear wave diffraction by a vertical bottom-mounted cylinder. The flow evolution is computed using a fourth-order Runge-Kutta scheme. Laplace's equation for the velocity potential is solved by a boundary element method. The free-surface conditions are applied on the actual water surface, the pressure on the cylinder is integrated over its actual wetted surface. We compute the nonlinear diffraction of steady periodic waves by a fixed surface-piercing circular cylinder. The prediction of the horizontal force acting on the cylinder is in good agreement with experimental observations and other numerical results.
