摘要
铸造凝固模拟技术已广泛地应用于生产实践中。多年来 ,对于此项技术的研究大都局限于数值求解的算法上 ,很少对数值结果的可视化进行专门研究 ,要促使CAE软件更加广泛地应用于铸造生产过程中 ,对其进行可视化开发是不可忽视的一项工作。在铸造CAE系统中 ,每次凝固模拟分析 ,划分的网格单元数 ,少则上百万 ,多则几千万。在基于OpenGL技术下 ,要获取令人满意的帧动画效果 ,应尽量缩减其绘制的网格数。本文重点介绍了表面搜索算法、表面网格合并算法等算法的实现。这些算法的成功实现 ,使得图形的实时显示成为可能。
The technology of solidification simulation of casting has been widely used in production. For many years, study on this technology focused on the algorithm of numerical method and especially the visualization of numerical results was less investigated. In order to make the application of CAE software in production more popular, the development of visualization is a very important job. On the CAE software, there are several or several ten million meshes in each analysis of solidification simulation. On based of OpenGL, in order to obtain content motive, we must decrease the drawing meshes. In this paper, algorithms of searching surface and combining of surface elements are introduced. The realization of these algorithms makes the real time display of numerical graph possible.
