【案例】SCDM抽取内流计算域

ANSYS SCDM提供了丰富的流体域创建功能，包括内流计算域抽取及外流计算域创建功能。本案例描述利用SCDM抽取内流计算域的基本流程。

• 启动SCDM，利用菜单文件 → 打开在弹出的文件选择对话框中打开几何文件Mainfold.scdoc

几何模型如图所示。

注：一般情况下，当导入几何模型后需要对模型进行清理，去除细小特征、修补破碎几何面等。本案例几何模型为清理完毕的几何模型。

• 点击准备标签页下体积抽取按钮激活内流计算域抽取功能

• 选择图形窗口中选择边按钮，如下图所示

• 选中几何模型中构成计算域进出口的4个圆，如下图所示

• 点击图形窗口中的完成按钮创建内流计算域模型

创建完成的几何模型如图所示。

• 右键选择模型树节点PartBody，选择弹出菜单项删除以清除原始几何

最终流体内流道计算域模型如图所示。

注：在SCDM中抽取内流道极为简单。本案例仅演示选取几何边的方式抽取内流道，其实也可以选择面来创建。
