Development of the Parallel Finite Element Method Code Using the Parallelized Plug-in Function and Performance Evaluation

Abstract

In recent years, more large-scale and complicated numerical analysis came to be performed in connection with fast development of technology. Such a large-scale problem is carrying out parallel computing, and has realized a short time and highly precise analysis. However, since the knowledge of parallel computing and experience are needed for development of a parallel analysis program, for a common user, it becomes the work which spends a remarkable labor and time. Then, in this study, the parallel FEM analysis code was developed using the plug-in function of GeoFEM. The plug-in function here is for developing parallel FEM analysis code without the knowledge of parallel computing. And parallel performance evaluation of the developed program was performed, and it checked that the high parallel performance of 80% or more of the rates of CPU usage came out also under a low communication performance like PC cluster.
