In this paper, a massively parallel multiphysics solver, based on an in-house massively parallel computing scheme for supercomputing, is developed for simulating large-scale antenna array and other 3-D structures, with domain decomposition method (DDM) also employed. During our simulation, frequency-domain electromagnetic fields are computed at first by solving the Helmholtz equation, and then the dissipated power is characterized, which is the heat source in the thermal co-simulation. New temperature profile can be obtained at the end of each iteration step, and they can be used to update all temperature-dependent parameters of the structure. This process is repeated until the temperature difference converge is achieved with a preset tolerance. The developed multiphysics solver is validated by comparing the results with that of commercial software. In particular, its speedup, scalability and efficiency are tested and examined. |
