本文描述了一种数值方法，用于求解含有II型超导体的器件内部的电流和场分布。二维解决方案的技术适应周围介质，包括铁的影响，并可以处理系统与任意数量的II型超导体和常规材料。该技术是基于有限元法，矩量法和临界状态模型。这项工作背后的推动力是对旋转电机的研究，这些电机包含与磁性材料和电流源一起放置的超导人工制品。在本文中，一个磁阻电机组成的铁转子两侧的两个高温超导片被选择来演示的方法。
A numerical method for solving for the current and field distributions inside devices containing type II superconductors is described. The two-dimensional solution technique accommodates the effects of surrounding media including iron and can handle systems with an arbitrary number of type II superconductors and conventional materials. The technique is based on the finite element method, the method of moments and the critical state model. The impetus behind this work is the study of rotating electrical machines which contain superconducting artefacts placed alongside magnetic materials and current sources. In this paper, a reluctance machine consisting of an iron rotor flanked with two HTS pieces is chosen to demonstrate the method.
