Outline of Final Research Achievements	A multi-scale simulation method for ship hydrodynamics has been developed based on the domain decomposition approach using multiple grid blocks. The different length scales and time scales are assigned in each block. In order to achieve the connections between blocks, the interpolation is used for the space domain, whereas the combination of interpolation and extrapolation must be adopted in the time domain to maintain time accuracy. By integrating the multi-scale simulation method for the space domain and the time domain, a generic multi-scale simulation method for ship hydrodynamics can be established.
