Massively Parallel Simulation of Large-Scale Electromagnetic Problems Using One High-Performance Computing Scheme and Domain Decomposition Method

Massively parallel simulation of large-scale electromagnetic problems is performed on a supercomputer using an in-house developed high-performance computing scheme together with a domain decomposition method, where parallel adaptive unstructured mesh generation is at first performed for modeling an arbitrary multiscale structure. The accuracy, speedup, as well as scalability of such parallel scheme are numerically tested and validated during its implementation for simulating electromagnetic environmental effects (E3) on a ship platform using the TianHe-II supercomputer. It is demonstrated that this method can overcome the convergence deficiency of conventional iterative solver. In addition, numerical experiments are also carried out to show its adaptability to the number of subdomains and object electrical size. It is believed that our developed solver can be further used for solving various E3 or electromagnetic compatibility problems for the design of many large-scale platforms.
