計算科学を用いたアナリシスとして有限要素法を用いた構造解析やシミュレーションが活用され始めて久しい。実現象、特に「ものづくり」における利用条件を想定したなかでの設計対象の構造分析をシミュレーションすることはやさしくない。一層合理的な設計対象の分析を可能とするために、シミュレーショ手続きを動的に管理制御し、創発的方法論に基づく設計対象の構造分析を「京」のような並列計算機を活用して、その考え方を実装した。その結果、適切な解析解の推定を可能とする見通しを得た。

In this paper, a numerical analysis's controlling and managing system is suggested, which controls the modelling process and data treating for structural robustness, although a numerical analysis's manager only controls a structural analysis by finite element method. The modeling process is described by the list of function ID and its procedures in a data base. The analytical modeling manager executes the process by order of the lists for simulation procedures. The manager controls the intention of an analysis by changing the analytical process one to another. Modeling process was experimentally found that may subject to the intention of designing index. In the numerical experiments, K, supercomputer is utilized by using parallel computing resource with the controlling and managing system.
