 混合网格 ON MIXED MESH FINITE ELEMENTS FOR SOLVING THE STATIONARY STOKES PROBLEM 解定常Stokes问题混合网格有限元 NOTES ON "ON MIXED MESH FINITE ELEMENTS FOR SOLVING THE STATIONARY STOKES PROBLEM 关于“解定常Stokes问题混合网格有限元”一文的注记 After that, the mixed mesh will be converted to fully quadrilateral mesh by Q-Morph method and optimized via existing optimizing methods with constraints. At last, numerical tests are given. 最后利用Q-Morph方法将得到的混合网格转化为全四边形网格,并用已有的优化方法对得到的网格进行带约束的网格优化。 According to the character of die shape, based on the mathematical model of multiple trimmed parametric surfaces, which is created by CAD/CAM system, an algorithm for generate mixed mesh of triangles and quadrilaterals for finite element analysis is presented. 根据冲压模具形状特点 ,对由CAD CAM系统建立的冲压模具的多裁剪参数曲面数学模型 ,提出了一种符合冲压成形有限元分析需要的三角形和四边形混合网格剖分算法 . The semi-staggered, non-equidistante non-orthogonal mixed mesh system is used by base of the characteristics of the method and the circular pipe with rapid-changed cross-section. 根据本方法和剧变截面圆管的特点,采用半交错不等距非正交贴体混合网格系。 Third component velocity was obtained by means of continuity equation. According to the characteristics of semi-false transient equations and flow region,the semi-staggered non-equidistant non-orthogonal curvilinear mixed mesh system was adopted in the numerical computation of the method. 根据半人工瞬变方程组的特点和流动区域的特性,本方法采用半交错不等距非正交曲线贴体混合网格系进行数值计算,并利用质点导数差分格式使计算更简便。 MIXED mesh method can be used all model which has similar features. 混合网格划分方法可以适用于所有具有类似几何特征的模型。
