東京大学、立命館大学およびプロメテック・ソフトウェアが共同研究をすすめている粒子法による津波の大規模3次元シミュレーションに関する共同研究の成果が、日本シミュレーション学会の論文誌「Journal of Advanced Simulation in Science and Engineering(JASSE)」に掲載されました。 [Journal of Advanced Simulation in Science and Engineering, Vol. 1, No. 1, (2014), pp. 16-35.] Development of Hierarchical Domain Decomposition Explicit MPS Method and Application to Large-scale Tsunami Analysis with Floationg Objects Kohei Murotani, Seiichi Koshizuka, Tasuku Tamai, Kazuya Shibata, Naoto Mitsume, Shinobu Yoshimura, Satoshi Tanaka, Kyoko Hasegawa, Eiichi Nagai, Toshimitsu Fujisawa -Abstract- In this research, a novel distributed memory parallel algorithm for the explicit moving particle simulation (MPS) method is presented. In this method, the analysis area is divided for distributed memory parallel computation using ParMETIS. The development offers two improved points from the distributed parallel explicit particle method of single bucket-based domain decomposition [1]. The first improved point is the hierarchical domain decomposition of two levels. The second improved point is that particle data are managed by buckets. Based on the improvements, we are efficiently able to run a large-scale run-up tsunami analysis. Comments are closed.
