Due to the recent development of computers, experiments have been replaced with computer simulations in various fields. Regarding this, the scale of the model to be solved tends to be extremely large. Notably, the power of engineering workstations (EWSs) have grown rapidly, and in order to perform large scale analyses with the EWS, the present authors have proposed 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 finite element analysis, the present authors have proposed a domain decomposition method combined with an iterative solver, where the entire analysis domain is divided into a number of subdomains without overlap. Using the present algorithm, the code for elastic-plastic finite element analysis is implemented on a network which is composed of several engineering workstations. Several tests are performed showing the high efficiency of the present method.
