摘要

波前拓扑系统(WTS)是一种在不同坐标系下生成三维网格的新算法。数学过程对所有几何坐标都是相同的。几何边界约束了网格拓扑的节点插入过程。结合局部索引和全局索引,可以同时生成任意几何域的坐标。这种独特的技术将证明与现有有限元方法的兼容性。由于该方法对各种坐标系和几何结构具有通用性,因此在电磁兼容建模中非常有用。对于电磁兼容的阐述,拉普拉斯方程将为分析提供一个自然的选择。稀疏模式将证明该算法的有效性。计算复杂度也与现有方法相当。结果将证明该算法的有效实现。

Wavefront Topology System & finite element method applied to orthogonal mesh structures
The Wavefront Topology System (WTS) is a novel algorithm which produces 3D grids in various coordinate systems. The mathematical procedure is identical for all coordinate geometries. The geometrical boundaries constrain the node insertion process for mesh topologies. In conjunction with local and global indexes, coordinates are simultaneously generated for arbitrary geometrical domains. This unique technique will demonstrate compatibility with existing finite element methods. Due to a universal approach for various coordinate systems and geometrical structures, the technique is useful in EMC modeling. For the exposition of EMC, the Laplace equation will provide a natural choice for analysis. The sparsity pattern will prove the efficiency of the algorithm. The computational complexity is also comparable to existing methods. The results will demonstrate an effective implementation of the algorithm.
