Hydrodynamic Pressure Distribution on Ship Hull At Very High Encounter Frequencies

New developments to improve the wave diffraction and radiation solution are presented in the present work. They consist of the implementation of the supplemented boundry intgral equation method to remove irregular frequencies, and the analytical integration of the wave terms in the Green function over a flat panel to ensure the numerical precision at high wave encounter frequencies. The hydro-structural interface is realized by recomputing the hydrodynamic pressure at points of structural model and the hydrodynamic pressure at points of structural model and the hydrodynamic coefficients (added mass and radiation following each mode of structural model. This provides a perfect equilibrium between inertial and pressure loads on the structural model.
