摘　　要：通过分析矩量法求解电磁问题过程和数据存储原理,推导出了模型网格数量与数据存储空间需求关系的近似计算公式,并用不同网格数量的车体模型仿真验证其正确性。实测与近似计算结果对比表明,矩量法电磁仿真存储空间需求近似计算公式在数千~数十万数量级网格模型条件下的估算误差小于1%。By analyzing the process for solving electromagnetic problems with MoM and the principle of data storage,the paper derives an approximate calculation formula for the relationship between the number of model meshes and the data storage space requirement,and verifies its correctness by simulation of car body models with different mesh numbers.The comparison between the actual measurement and the approximate calculation results shows that the estimated error of the approximate calculation formula of the storage space requirement for the electromagnetic simulation of MoM is less than 1%under the grid model of the order of thousands to hundreds of thousands.
