本文提出了一种新的方法，用原始变量而不是磁矢势数值求解导电材料中的电磁感应方程。求解电场的分量允许网格域仅覆盖被处理的材料，而不是在空间中进一步延伸。与有限体积离散化一起，这使得电磁求解器在多物理场仿真框架内的无缝耦合成为可能。通过对已知结果的算例进行验证，给出了感应加热三维工业应用实例，表明了该方法对实际工程计算的适用性。
A new method is presented for numerically solving the equations of electromagnetic induction in conducting materials using native, primary variables and not a magnetic vector potential. Solving for the components of the electric field allows the meshed domain to cover only the processed material rather than extend further out in space. Together with the finite volume discretisation this makes possible the seamless coupling of the electromagnetic solver within a multi-physics simulation framework. After validation for cases with known results, a 3-dimensional industrial application example of induction heating shows the suitability of the method for practical engineering calculations.
