Outline of Final Research Achievements |
In this research, the development of the large scale distributed memory parallel framework for the particle method and the quantitative and qualitative estimation of tsunami damage for ground structure are performed. In case of large scale distributed memory parallel framework for the particle method, the development and estimation of the fast computational algorithm for CPU/GPU/MIC and the high precision semi-implicit solution of the MPS method are performed. In case of the quantitative and qualitative estimation of tsunami damage for ground structure, the structural integrity is estimated using the structure analysis with external force by tsunami wave pressure for the station building in Kesennuma urban area is performed. Additionally, the floating analysis of 33 cars by tsunami is performed. The research product is published in WEB as the open source software named "LexADV_EMPS".
