Computer simulations are about to replace experiments in various fields. Regarding with this, the scale of model to be solved tends to be extremely large. In order to perform such large scale analyses, the authors propose the parallel use of several computers connected to a network. In other words, a computer network is regarded as a parallel computer. As a parallel numerical algorithm for the fimite element analysis, the present authors have proposed a domain decomposition method combined with an iterative solver, where a whole analysis domain is ficitiously divided into a number of subdomains without overlapping. The present algorithm is first implemented on a network composed of several engineering workstations, and the efficiency is confimed on the EWS network. The system is then successfully applied to the analysis of a sample problem of the order of one million degrees of freedom by using a supercomputer network which consists of several supercomputers.
