PARALLEL STRESS ANALYSES OF ANCIENT ARCHITECTURE PANTHEON ON PC CLUSTER
Tomoshi Miyamura, Shinobu Yoshimura · Journal of Structural and Construction Engineering (Transactions of AIJ) · 2001
Parallel finite element stress analyses of Pantheon are conducted on a PC cluster. The authors are involved in a project in which a parallel computational mechanics system including pre-, main-, and post-processing modules based on the domain decomposition are being developed. Geometry models are first created by using a 3D CAD, and then fine meshes with tetrahedral solid elements are automatically generated. The static stress analysis with a mesh of 18 millions DOFs, and elastic-plastic stress analysis and seismic response analysis with meshes of several million DOFs are conducted. The results are visualized by the parallel post-processing module. Not only the effectiveness but also some problems in the large-scale analyses of architectural structures are described as concluding remarks.
