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.enPreprintship hydrodynamicsfree surfacefully nonlinear potentialBoundary Element Methodsemi-LagrangianCAD surfacesautomatic mesh generationMAT/08 ANALISI NUMERICA
