摘要
本文是文献[1]的继续。针对二维恒定磁场的边值问题,通过一系列模型题的计算,得到自适应有限元计算时估计误差和实际误差的关系曲线;使得不存在解析解的工程问题,只要算出估计误差,即可由此确定实际误差的值,从而解决了工程上普遍关心的有限元磁场计算的精度问题,为设计和研究工作提供了可靠的依据。
This paper is part Ⅱof a former paper [1].On the basis of calculation of severalmodel problems of 2D stationary magnetic field having analytic solution,the relation be-tween the actual and estimate gfobal errols is obtained. From this relation, for anyengineering problem, upon calculate the estimate error, the vaiue of actual global errorcan be predicated and the accuracy of FE computation generally concerned is deter-mined. Thus a reliable basis for design and research work is provlued.
