Outline of Final Research Achievements |
A finite element analysis using the high-fidelity model is expected to be able to further improve the reliability of the earthquake and tsunami hazard analysis. However, it was too difficult to conduct such a finite element analysis due to its huge computational cost since the target domain is huge and its required resolution is very fine. This research has developed a new method for constructing a huge-scale finite element model and a new finite element analysis method for computing responses of such huge finite element models enhanced by adaptive preconditioner, mixed precision computation and fine-coarse solution space constrain etc. These new methods on hetero-computing environment with CPU and GPU show several application examples which present effectiveness of a finite element analysis using the high-fidelity model.
