In the coastal engineering field, the particle method is expected to give a breakthrough for three dimensional numerical simulations on wave breaking and flui d-structure interaction. Although some researches show that particle method has less accuracy than both finite element method and finite difference method. The particle method (MPS method) has, however, frequ ently been used as a useful simulation tool in analysis of complex three dimensional water flow. The authors analytically propose a new calculation model of the gradient operator for the MPS method. The numerical results using this new model show high accuracy and computational stability. The MPS method with this high accuracy can disclose the occurrence of wave breaking of a standing wave generated in a water storage tank.
