Abstract: We have been developing an efficient algorithm based on a geometrical multigrid approach, named “Multi-level Hierarchical Domain Decomposition Method” (MHDDM), for the large-scale finite element analysis. A MHDDM has a multi-level hierarchical structures of subdomains and make a coarse-grid-based preconditioner easy to apply for the large-scale analysis. In this paper, we performed benchmark test using some test models and assume the relation between the number of subdomains and the number of DDM iteration and threshold of residual.
