摘要

在非结构四面体网格上进行电磁仿真的优点是可以获得光滑的边界近似和无缝的多尺度网格划分。然而,通常情况下,规则单元的计算效率明显更好,因此在实践中混合网格通常提供最有价值的整体方法。在本文中,我们考虑了一个特定的四面体散射单元的范围,它既填充空间又具有计算效率,可以在TLM模拟中实现。

Regular space filling tetrahedral elements for transmission line modelling (TLM)
The advantages of electromagnetic simulations operating on unstructured tetrahedral meshes are the availability of smooth boundary approximations and seamless multi-scale meshing. However in general, computational efficiency is notably better with regular elements and therefore in practice hybrid meshes usually provide the most valuable overall approach. In this paper we consider the scope of a particular tetrahedral scattering element that is both space filling and computationally efficient to implement in TLM simulations.
