This paper presents the formulation of a boundary element analysis method for handling contact problems, and the technique for high-speed contact analysis using a supercomputer. This formulation is based on the idea of joint blocks for joining adjacent blocks, and it indicates contact states. Contact analysis for obtaining contact states requires an iterative process. This process is normally very time-consuming. We introduce a new, faster technique for carrying out this process. The required supercomputer CPU time for this process is examined. The iteration time with the new technique is about one-tenth that of the conventional process.
