摘要
研究了基于三棱柱剖分单元的电磁场有限元结果的后处理,给出了内部结果的剖切显示方法,通过将三棱柱单元细分为四面体单元,使三棱柱单元的等值面提取转化为简单的四面体单元的等值面提取,简单、实用地解决了单元细分时的相容性问题。最后介绍了利用OpenGL图形功能显示三维模型消隐的方法。
In the paper, post-processing techniques of finite element results based on tri-prism elements for electromagnetic field are studied. A method of cutting and display of 3D finite element model and interior results is present. Isosurface extracting of tri-prism element is converted to isosurface extracting of tetrahedron element by dividing a tri-prism into three tetrahedrons. A simple method is adopted in solving compatibility problem of neighboring elements. In the last, the paper introduces the method of utilizing OpenGL to realize display and hidden line removal of 3D model.
