Time-domain computations for floating bodies

Abstract

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 hydrodynamic forces acting on floating bodies is presented. Both linear and fully nonlinear computational techniques are presented. The linear problem is solved using a time-domain Green function approach. The fully nonlinear computations are done using an Euler-Lagrange method. At each time step the resulting mixed boundary value problem is solved using a desingularized isolated source. Results are presented for simplified bodies.
