TIME-DOMAIN COMPUTATIONS FOR FLOATING BODIES

A review of the research carried out at the University of Michigan and elsewhere on the use of time-domain panel methods to compute the hydr odynamic forces acting on floating bodies is presented. Both linear an d fully nonlinear computational techniques are presented. The linear p roblem is solved using a time-domain Green function approach. The full y nonlinear computations are done using an Euler-Lagrange method. At e ach time step the resulting mixed boundary value problem is solved usi ng a desingularized isolated source. Results are presented for simplif ied bodies.
