Abstract

An expository review is given on three major types of numerical methods commonly used in free-surface and body interaction problems of the deterministiccype. The general principles governing boundary-fitted coordinates are described. Formulations commonly used for finite-element type methods are explained. Boundary-integral equation methods of various forms are discussed. Special attention is paid to features of each type of methods that are efficient and potentially attractive and also to features that are known to be problematic. Various current research activities in time-dependent type solutions are briefly summarized. A novel idea involving the new concept of “shell functions” in unsteady problems is proposed. Once properly calculated, the “shell coefficients” can be used for a large number of methods and for arbitrary body geometry.
