论文摘要
尽管计算电磁学的迅速发展的领域，但很少有开源工具能够解决自动网格生成问题，从而将感兴趣的问题正确离散为有限的元素（单元）。尽管在计算物理领域已经建立了几种网格生成算法，但绝大多数此类工具仅针对四面体网格形成，而预期的主要应用是有限元方法。在这项工作中，提出了用于电磁模拟的计算有效的非均匀结构（直线）网格生成算法。我们检查了针对先前工作的速度，性能和适应性，并评估了其与商业生成网格的复杂几何形状案例的鲁棒性。发现使用该方法的生成网格产生的网格和仿真结果被认为是坚定的一致性。
Despite the rapidly evolving field of computational electromagnetics, few open-source tools have managed to tackle the problem of automatic mesh generation for properly discretizing the problem of interest into a finite set of elements (cells). While several mesh generation algorithms have been established in the field of computational physics, the vast majority of such tools are targeted solely towards tetrahedral mesh formation, with the intended primary application being the finite element method. In this work, a computationally efficient non-uniform structured (rectilinear) mesh generation algorithm for electromagnetic simulations is presented. We examine the speed, performance and adaptability against previous work, and we evaluate its robustness against a complex geometry case with a commercially-generated grid. The mesh and simulation results produced using the generated grids of the proposed method are found to be in solid agreement.
