Abstract
In the coastal engineering field, particle method is expected for three-dimensional numerical simulations on fluid-structure interaction. Although in realistic three-dimensional numerical simulation, an increase of memory utilization and a computational time are very serious problems due to resolution of distance of particles and increase of number of particles. In this research, the authors develop a hybrid (openMP/MPI) parallel simulation code of MPS method and simulate large-scale simulations for coastal engineering. The simulation of a static water problem evaluates the parallel performance of the proposed simulation code. And the simulation of a collapse of water column and the progressive wave verifies the accuracy. The result of large-scale simulation of ocean wave showed the wave concentration into cavities of structures, and generation of spray as three-dimensional hydraulic phenomenon. This study shows that we can evaluate three-dimensional hydraulic phenomenon more fully with the proposed simulation code.
