Distributed parallel computing using PC cluster is applied for the actual configuration of nuclear power piping system. Actual configuration is modeled in 3-dimensional modeling leading to very high degrees of freedom to be indispensable for the use of parallel computing. First of all, the employed elements, such as 4-node tetrahedron element and 8-node hexahedron element are examined for their accuracy in structured mesh subdivision. The pipe bend and T-pipe are modeled by hexahedron elements, and analyzed in elastic-plastic large deformation case. The obtained numerical results agree well with experimental results.
