本文介绍了一种新的移动不匹配重叠网格有限元砂浆法。对于运动部件的每一个新位置，实现了固定子域和运动子域之间的信息双向传递。给出了两个数值例子来支持该理论：1)一个已知解的静电问题，说明了该方法的最优性；2)涡流无损检测配置，强调了所提出方法的灵活性和效率。
In this paper, a new finite element mortar approach with moving nonmatching overlapping grids is introduced. The bidirectional transfer of information between the fixed and moving subdomains is realized for each new position of the moving part. Two numerical examples are presented to support the theory: 1) an electrostatic problem with known solution, to state the optimality of the method and 2) an eddy current nondestructive testing configuration, to underline the flexibility and efficiency of the proposed approach.
