Huge facilities are often built along coastal regions, such as petrochemical and nuclear power plants. However, these plants near to the sea are vulnerable to water-related disasters, especially when the tsunami occurred by great earthquake. An objective of our research is to estimate the effect of tsunami inside building.We apply the approach of MPS-FE method to solve the fluid-structure interaction problems This method adopts the Moving Particle Simulation (MPS) method for fluid computation and the Finite Element Method (FEM) for structure computation.In past research [1], the large-scale tsunami analysis on urban area for ground structures and floating objects was done. In this research, the tsunami inundation analysis into the interior of a building is done. Furthermore, the fluid-structure behavior is analyzed to estimate the damage inside the building caused by tsunami.We use the ADVENTURE_Solid ver.2.0 for the structure computation and the LexADV_EMPS ver.0.1.2b for the fluid computation. In this research, the Japan’s petaflops supercomputer, K computer is used as computational platform.
