Abstract

This document presents a new electromagnetic in-house parallel EM simulator named HOFEM (Higher Order Finite Element Method). The simulator makes use of some of the research developments on the area made within the Group of Radiofrequency, Electromagnetism, Microwaves and Antennas (GREMA) of the Universidad Carlos III de Madrid to which the authors belong to. HOFEM makes use of a weak formulation based on double curl vector wave equation discretized with the higher-order isoparametric curl-conforming tetrahedral (and prisms) finite element rigorous implementations of Nédélec's first family of elements. A non-standard mesh truncation technique, FE-IIEE (Finite Element - Iterative Integral Equation Evaluation) for open region problems provides an arbitrarily exact absorbing boundary condition while retaining the original sparse structure of the FEM matrices. The simulator provides a multi-platform (Linux & Windows) user friendly graphical user interface. Remote job submission to HPC clusters is supported by integrating an in-house software tool developed for this purpose.

HOFEM:一种高阶有限元电磁模拟器

本文提出了一种新型的室内电磁平行仿真器HOFEM(高阶有限元法)。该模拟器利用了作者所在的马德里卡洛斯三世大学射频、电磁、微波和天线组(GREMA)在该领域的一些研究进展。HOFEM采用基于双旋度矢量波动方程的弱公式，用高阶等参旋度四面体(和棱镜)有限元离散化，严格实现nsamdsamlec第一族单元。FE-IIEE(有限元-迭代积分方程评估)是一种非标准网格截断技术，它在保留有限元矩阵原始稀疏结构的同时，提供了任意精确的吸收边界条件。该模拟器提供了一个多平台(Linux & Windows)用户友好的图形用户界面。通过集成为此目的开发的内部软件工具，可以支持向HPC集群提交远程作业。
