A method - heaping method, which uses background lines to determine generation orient of quadrilateral elements is presented. The method is me simple than paving method in structure and more fast in speed because it avoids crosses and intersections between elements layers.In this paper,basic theory of heaping method is first introducede. Secondly, two examples are given. At last, its performance is evaluated.

提出了一种使用背景线指示网格生成方向的网格生成技术─—堆砌法,用四边形网格划分任意二维区域。生成的网格质量较好,单元形状接近于正方形,边界单元的边趋向垂直于边界。与目前四边形网格划分效果较好的铺路法相比,算法结构简单,执行速度快。首先说明了这种算法的基本理论,然后对这种算法的性能进行了评价,最后给出了两个用这种算法获得的网格的例子。

It is more difficult to generate quadrilateral elements than to generate triangular meshes. This paper presents two algorithms to generate quadrilateral elements. One algorithm covens the triangular quadri-lateral elements into quadrilateral elements, the other algorithm uses the mapped element approach to generate quadrilateral elements. Both of the two algorithm has the property of high computing efficency and good quality.

有限元四边形网格划分要比三角形网格划分难很多,这里通过两种方法解决四边形网格划分问题。一种是把已有三角形网格转化为三角形/四边形混合网格,另一种是通过映射法生成全四边形网格。两种方法都具有计算效率高,四边形网格质量好的特点。

The necessity of train aerodynamic experim en t data visualization, algorithms of scalar data and vector data visualization ar e briefly introduced. Surface field scattered data visualization method based on streamline shape of train is emphasized. The dividing quadrilateral grid algori thm is adopted to divide the scattered data field in the form of quadrilateral g rid. Through the coordinate conversion, bend surfaces are converted into planes, then the interpolation is performed. The interpolated value obtained by isomet ric scanning is mapped from calculated coordinate to actual coordinate. This me thod can avoid many defects such as the interpolated value is convergent when it is obtained by isometric scanning in actual coordinate. On the basis of object -oriented software engineering thinking, the visualization system of the experi ment data is achieved by using the above-mentioned method. The program class de finition is described with C++ language and application cases of the data visual ization system are presented.

简述列车气动试验数据可视化的必要性,介绍标量场、矢量场这两类实验数据可视化算法,着重讨论基于流线型列车外形的曲面域散乱数据场可视化方法。采用四边形网格划分算法将散乱数据场网格化,应用坐标转换法将曲面域转换为平面域进行插值计算,在计算坐标系中等距扫描插值再映射到实际坐标系中对应点,克服了在实际坐标系中等距扫描插值算法是否收敛等缺陷。据此采用面向对象的软件工程思想编制了试验数据可视化系统。用C++语言描述了程序中类的定义,给出可视化系统的应用实例。
