Abstract
Coupled finite element analysis is expected in several fields of research and development, where necessity of coupled analysis of not only two phenomena but also three or more phenomena is increasing. The demand for multiscale and multiphysics analyses is also increasing. A coupled analysis approach that combines an in-house code and a general-purpose commercial finite element analysis code using a message passing interface is very promising for these analyses. To examine the practical usefulness and effectiveness, this approach was applied to the triply coupled and multiscale analyses of a resistance spot welding problem and to the dynamic coupled analysis of an ultra sonic piezoelectric motor. The approach is effective to perform various types of coupled finite element analyses of multiphysics and multiscale problems.
