Abstract

We present a large-scale parallel complete domain decomposition method (CDDM) based hybrid finite element-boundary integral-multilevel fast multipole algorithm (FE-BI-MLFMA). The finite element subdomain interfaces employ second-order Robin transmission conditions, while the internal finite element parts and the external boundary integral surfaces use first-order Robin transmission conditions. The boundary integral equation part employs the discontinuous Galerkin domain decomposition technique. The entire finite element solution domain is divided into larger subdomains, each of which is assigned to an MPI process. Then the larger subdomains are evenly divided into smaller subdomains to achieve optimal computational efficiency. Two examples are provided to demonstrate the accuracy and efficiency of the large-scale parallel CDDM algorithm, including a large-scale antenna array.
