Abstract
The problem of determining the exciting forces acting on a rigid floating body due to uni-directional waves has been extensively studied. The problem is usually formulated in the frequency domain by assuming that the incident waves are sinusoidal and of fixed frequency. Results for more general wave systems may then be found using superposition and Fourier analysis. In this paper the problem will be formulated in the time domain. Numerical techniques are developed for bodies of arbitrary shape. The solutions in the time domain and frequency domain are related through the use of Fourier transforms.
