摘　　要：模拟电磁场FDTD网格的可视化是解决电磁学问题的一种有效方法,而有效网格的自动生成算法是其中最关键的技术.为此基于对称曲线提出了一种非均匀FDTD网格的划分算法,采用此方法生成的网格不仅精确,而且快速有效,有利于提高网格计算的精确度,适用于一般的电磁场网格生成系统.Electromagnetic simulation and visualization based on non-uniform FDTD mesh is an efficient method for solving many electromagnetic problems and it is important to use a good algorithm to produce reasonable and suitable mesh. An algorithm based on the symmetrical curve is thus proposed. Grids produced with the algorithm are not only accurate, but also fast, and the precision of mesh computation is also enhanced. Therefore, it can be used for general mesh producing systems.
