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。
Foundry solidification simulation technology has been widely used in production practice. Over the years, most of the research on this technique has been limited to the algorithms of numerical solution. It is seldom to study the visualization of numerical results very much. It is necessary to promote the CAE software to be more widely used in the casting production process. Ignore a job. In the casting CAE system, each solidification simulation analysis, the number of grid cells divided, ranging from a few million, as many as tens of millions. Under the OpenGL technology, to get a satisfactory frame animation, you should try to reduce the number of grids it draws. This article focuses on the surface search algorithm, surface mesh merging algorithms and other algorithms. The successful implementation of these algorithms makes the real-time display of graphics possible.
