摘要
针对边界面法分析模型前处理过程中边界条件的加载,提出了一种基于UG/Open的可视化算法。算法首先利用UG系统中几何模型的边界表征数据,在参数空间生成背景网格并计算显示点的坐标,然后再映射到三维空间进行图形显示,映射后能够保证几何信息的准确性。该算法不仅实现了与UG系统的无缝连接、载荷和位移约束条件的自动显示,而且有利于实现CAD和CAE模型的一体化。
This paper proposed a visualization algorithm based on UG/Open for the loading of boundary conditions during the pre-processing of the boundary face method analysis model. The algorithm firstly used the boundary representation data of geo- metric model in UG system to generate the background grid and calculated the coordinates of the display points in the parame- ter space. And then these coordinates were mapped to the three-dimensional space for graphical display. This mapping could guarantee the accuracy of geometric information. This algorithm not only achieves the seamless connection with UG system, au- tomatic display of load and displacement constraints, but also facilitates the integration of CAD and CAE models.
