OSCILLATIONS AND WAVE FORCES IN A MAN-MADE HARBOR IN THE OPEN SEA
This paper describes a numerical method using finite elements developed for computing waves and wave forces inside an offshore harbor in communication with the open sea. A mixed method is used whereby the far field and the neighborhood of the tip of a thin breakwater, if any, are represented analytically, and the remaining fluid region is treated by finite element approximation. A comparison with analytic solutions to problems of simple geometry is used to guide the choice of the element size. Mean harbor response and exciting forces on the platforms have been calculated for the case of uniform depth where all solid objects are vertical-walled and bottom-seated, and for the case of shallow water waves using the approximate formulation of John.
