摘要

从磁动力学的磁场公式出发，考虑导体内部的有限元法与边界积分法的耦合，以描述外区。我们研究了三种不同的离散化:每条边一个变量，每条边两个变量和节点变量。在每种情况下，我们确定了磁场h和电流j =旋度h的精度，作为网格尺寸和CPU时间的函数。我们推导出最适合计算每个物理量的变量。

3D modelling of electromagnetic fields: advantages and disadvantages of nodal or edge elements

Starting from the magnetic field formulation of magnetodynamics, we consider the coupling of a finite element method in the conductors with a boundary integral method for the description of the exterior region. We examine three different discretizations: one variable per edge, two variables per edge and nodal variables. We determine the precision on the magnetic field h and the current j = curl h as a function of the dimension of the mesh and of the CPU time in each case. We deduce the best–suited variable to the computation of each physical quantity.
