Zusammenfassung:The invention discloses an efficient parallel computing simulation method for filtering a local discontinuous domain based on OPenSeesMP, and aims to solve the problem that in scientific research and practical engineering, due to grid size jump, the computing iteration convergence is poor in site-structure system interaction. According to the method, the structure-site interaction near field domain and the free field domain are divided by adopting different grids and different sizes, and the weighted average method is utilized to perform data transmission real-time interaction on the far field region nodes and the near field region calculation information, so that the calculation time can be greatly shortened, the consumption of calculation resources is reduced, the calculation efficiency is improved, and the calculation efficiency is improved. Therefore, the method has a wide application prospect. The feasibility of the method is verified through a large vibration table test of a liquefaction site-pile group
