Abstract

We present a model for ship hydrodynamics simulations currently
under development at SISSA. The model employs potential flow theory
and fully nonlinear free surface boundary conditions. The spatial
discretization of the equations is performed by means of a collocation
BEM. This gives rise to a Differential Algbraic Equations (DAE)
system, solved using an implicit BDF scheme to time advance the
solution. The model has been implemented into a C++ software able to
automatically generate the computational grids from the CAD geometry
of the hull. Numerical results on Kriso KCS and KVLCC2 hulls are
presented and discussed.
