| Research Abstract |
To reduce costs and improve accuracy of large-scale numerical simulation of structural strength analysis, as a numerical parallel numerical algorithm suitable for a petascale computing, a parallel finite element analysis system ba sed on a balancing domain decomposition was developed. As a result, a static stress analysis of a large-scale plant with about 200 million degrees of freedom mesh was successfuly performed in about 1 minute on the K computer of 3, 000 nodes.
