摘要
本文提出了一种电磁场有限元计算后验误差估计和自适应新方法，深入研究了电磁场有限元后验误差估计中误差模的选择和不同材料区域交界面切的不连续性的处理等问题，给出了一种网格自适应生成控制参数的计算方法，通过与作者提出的全自动自适应网格生成算法相结合，对一些二维电磁场问题，实现了全自动自适应有限元分析。文中给出的一些实例计算结果表明了本文方法及相应软件的具体性能。
a new posteriori error estimator and adaptivity approach for electromagnetic field finite element computations are proposed- The problems about the selection of the norm of the error estimator and the discontinuities of fields at the interfaces of various material regions are considered. The method for obtaining the control parameters of mesh adaptive generation is given out. The automatic adaptive finite element analyses for some 2D electromagnetic field problems are realized thought the integration of the error estimator and the fully automatic adaptive mesh generator proposed by the authors. bome examples are provided to show the per formances of the proposed posteriori error estimate and adaptivity approach and the implemented program code.
