准静态电磁场计算的两步达尔文模型时域公式
A Two-Step Darwin Model Time Domain Formulation for Quasistatic Electromagnetic Field Calculations
摘要：
在没有波传播的情况下，瞬态电磁场由准静态达尔文场模型的复合标量/矢量势公式控制。达尔文型场模型能够捕获电感、电阻和电容效应。为了避免可能的非对称性和病态的完全离散的单片配方，在这里，达尔文场模型的结果，在两步算法，连续计算的电标量位和磁矢量位的离散表示。数值模拟验证了该方法的有效性。
英文摘要：
In the absence of wave propagation, transient electromagnetic fields are governed by a composite scalar/vector potential formulation for the quasistatic Darwin field model. Darwin-type field models are capable of capturing inductive, resistive, and capacitive effects. To avoid possibly non-symmetric and ill-conditioned fully discrete monolithic formulations, here, a Darwin field model is presented which results in a two-step algorithm, where the discrete representations of the electric scalar potential and the magnetic vector potential are computed consecutively. Numerical simulations show the validity of the presented approach.
