F601 SPH粒子法による津波解析(F6.防災・減災に向けて計算力学はいかに貢献できるか,フォーラム)

Tsumani simulations by particle methods have been performed using a real geometry of sea side area of Shonan district. In this study SMAC-SPH method which is one of the incompressible viscous flow analysis has been used to solve the big wave motion on the coast area. We used the map contours to make three dimensional data of a bay side area, and the houses and buildings were modeled on the land geometry. The results of the Tsunami simulations have been visualized using CG techniques. It was concludede that the details of Tsunami behaviors on a bay side area have been cleared by SPH particle analysis.
