Electromagnetic-thermal co-simulation of large antenna array on platform is performed using in-house enhanced finite element solver with massively parallel computing capability. It appropriately integrates both domain decomposition method (DDM) so as to solve very large complex matrix efficiently during the implementation of finite element procedure. Its massively parallel computing capability is examined on the supercomputer, where the antenna arrays of $16^{\ast}16$ operating at 2.5 GHz, together with their platform are simulated, respectively, and its accuracy is validated in comparison with the numerical result obtained by commercial software but just with small scale. The computational efficiency of such in-house developed solver can reach a speedup of 7.149 and strong scalability efficiency of 64.2% on 512 CPU cores of 32 computing nodes, and its speedup, scalability and efficiency are also examined. In particular, not only the radiation characteristics but also the surface temperature distribution of large antenna arrays are for the first time addressed in the high –power operating state, which directly support their reliability design. |
