网格划分实例.pptVIP

* * * * * 检查网格 检查网格 膨胀 – 管壁上 尺寸 – 面上4个单元 尺寸 – 单元尺寸 1mm越过管 p并偏斜来在过渡区域增加密度 2D Fluent 分析的表面体网格划分 作业8.1 这个作业示范对一2-D混合肘生成网格的过程。 混合肘结构是通常在动力设备中遇到的2-D 表示的管系统。混合区域附近的流场和温度场是CFD分析者所关心的。 目标: 向ANSYS 网格程序输入在 DesignModeler创建的2D 几何 对表面体创建 2-D 网格 目标 长度单位是 mm 输入几何 从指南文件夹将 mixingelbow.agdb文件复制进你的工作目录 启动Workbench 并双击Component Systems面板的Mesh项 右击 项目示图区中Mesh 中Geometry 并选择 Import Geometry/Browse 浏览复制的mixingelbow.agdb文件并点击Open，注意这时Geometry有一个绿色对号标记，暗示几何已经被定义 设置划分方法 双击项目示图区Mesh对象中 Mesh项打开ANSYS网格划分 在Meshing Options面板将 Physics Preference设为 CFD 并选择 Automatic 网格划分方法，然后点击 OK 4 个表面体 设置边尺寸 右击Outline中 Mesh, 并选择 Insert/Sizing，将 Selection Filter 改为 Edges 并选择如图所示4条边 设置边尺寸Type 为 Number of Divisions 并输入 10， Behavior 设为Hard. Bias Type 设为shrink towards the edges 且 Bias factor为10 对如图所示其它边重复以上过程 设置边尺寸 设置边尺寸 映射面划分和网格 如图插入 Mapped Face Meshing. 选择所有的四个面 生成网格， 注意边尺寸的类似膨胀方法 * * * * * * * * * I’d like to remind everyone that some matters that will be discussed during this presentation may constitute forward-looking statements that involve risks and uncertainties, which could cause actual results to differ from those projected.
