Performance of large scaled tsunami run-up analysis using explicit ISPH method

Abstract

The tsunami run-up simulation by the particle method at city level needs to huge number of particle at least 1 billion particles. The conventional particle simulation method is not easy to solve these huge problem even on the premise of using supercomputer. Then, a new particle method ’fully explicit Incompressible SPH’ is developed that takes into consideration both calculation efficiency and accuracy. Finally, we demonstrate the future plan how to use our simulation resultes for a practical ’Soft’ disaster mitigation method through the evacuation education with the Virtual Reality(VR) system
