摘要
计算技术的进步使日益复杂、高维问题的分析得到解决，但由此产生的数据量也日益庞大，需要恰当的可视化方法来表述这些数据的含义。尤其是矢量场，不仅要表示出场量的大小，还要表示出方向、位置以及流线。至今为止，三维矢量场的可视化问题还没有得到很好的解决。介绍了电磁场有限元分析的后处理中，矢量场的可视化技术，提出了应用多种方式、多个侧面地表述空间矢量的方法，并以三维涡流场有限元的后处理为例，验证了该方法的可行性。
Recent developments in computational techniques make the analysis of complex and three dimensional electromagnetic problems possible, the analyses usually result with a large amount of data, which is usually difficult to be interpreted without good visualization techniques. For vector field, not only its magnitude, but also its direction, loci and the streamlines, should be visualized. But, visualization for 3D vector field has not been solved perfectly till now. In this paper, visualization techniques of vector field for FE post-processing of electromagnetic field are introduced. Multi- way and multi-aspect method is presented to recognize the spatial vector field. An example of 3D eddy-current post-processing for FE analysis is given.
