摘要:
有限元理论及技术对于求解大规模有限元方程至关重要的快速算法研究尚存许多问题.提出了一种目标区域定位算法并与波阵法联合使用的新数值技术,分析了新算法的原理及其在非线性条件下的应用.阐述了在磁矢量(MVP)有限元中的实现,最后给出计算实例.结果表明,采用新方法可以节约大量计算机资源,是一种鲁棒性较好的数值技术,对大规模电磁场数值计算也有良好的应用前景.
Abstract:
F inite e lem en tm ethod ( FEM ) is pow erfu l fo r nume rical ana lysis and has been w ide ly and successfu lly used in num er ica l electrom agne tic ana lysis. On the o ther hand, the so lve r deve lopm ent, wh ich is also very important in so lv ing large-sca le FEM equations, still seem s not as w ell-researched as that of mode l deve lopm ent. In th is pape r, an num er ica l techn ique o f target-reg ion loca ting ( TRL) is presented and app lied in finite elem entm ethod for 3D e lec- trom agne ticm odeling. The pr inciple o f new so lver and its availability for non-linear use a re demonstra ted, show ing that it can be eas ily used w ith e fficiency. A lso the imp lem enta tion in FEM based on m agnetic vecto r po tential is intro- duced. F ina lly a num er ica l examp les o f 3D m agnetostaticm ode ling is g iven w ith the com parison o f computer resource used be tw een new so lver and comm ercia l softw are, seeing that a huge com puter resource can be saved by emp loy ing new so lver. Besides tha t, th ism e thod can also be extended to othe r quasi-static applications
