Abstract:
In this research, a system of thermal-solid coupling analysis was developed with the implementation of Balancing Domain Decomposition (BDD) in both thermal and solid analysis. The developed system performed heat conductive analysis to have temperature distributions in solid models and then performed the structural analysis to see deformation or expansion due to temperature differences. Both of the analyses employed the Hierarchical Domain Decomposition Method (HDDM) with parallel BDD type pre-conditioner. It is shown that the iterative procedure converged rapidly and the convergence was independent of the number of subdomains, namely, numerical scalability was satisfied. The present system was implemented on parallel processors and succeeded in solving a thermal-solid coupling problem of a High Temperature Test Reactor with 1.9 million nodes.
