Abstract
A set of Fortran programs has been developed for the time-domain prediction of wave-body interactions, including hull motions and hydrodynamic loads, in three dimensions. Three separate programs address the problems of hydrostatic equilibrium, hydrodynamic impulse response characteristics and the longitudinal equations of motion. Hydrostatic equilibrium is determined by solving either for the draft at midships and trim of stern, or by calculating the equilibrium displacement, given the draft and trim. Hydrodynamic impulse response characteristics are determined by solving separate bound integral equations for the surface velocity potentials using a collocation method in a hull fixed coordinate system.
