The applications of Computational Fluid Dynamic (CFD) based on Navier-Stokes equations in ship and offshore hydrodynamics are still limited due to the heavy computational time. Potential-flow models are much faster compared with typical CFD solvers. It appears natural to apply the CFD in the region where the non-potential-flow effects matter (e.g. viscous flow separation and local wave breaking), and to solve Laplace equations elsewhere (See for instance Colicchio et al.  and Kristiansen & Faltinsen ). Many free-surface problems involving large volume structures are dominated by potential flow effects in the whole water domain. The objective of this study is to find an efficient numerical method to solve the fully-nonlinear potential-flow problems with the presence of free surface and a body. The problems considered in this abstract are in 2D. However, the experiences should also be useful guidance in 3D studies.
