Abstract The purpose of this study is clarifying the magnitude of force generated by the tsunami including a lot of debris by simulation. We calculated the free surface flow using Lattice Boltzmann Method and phase-field method. Lattice Boltzmann Method is one kind of weekly compressibility solutions and is suitable for large scale simulation because its algorithm is easy. And we used phase-field method for interface capturing. In this simulation, we have many GPUs in parallel and made large-scale calculations. The results of this simulation show that the collision force between floating debris and wall is very larger than the wave force.
