简单记录一下，主要是filter的应用
details：
computational domain of size is [0, 2.2] × [0, 0.41].
The centre of the cylinder is located at (0.2, 0.2).
cylinder diameter (L) is 0.1 units.
Process
- 加载.vtu 文件组
- Filter-> ExtractSurface: 提取外表面
- Filter-> FeatureEdges: 从输入数据集中提取边缘子集
- Filter-> Clip: 把圆柱切出来
Clip Type: Sphere
Point Cloud Parameters: Center[0.2, 0.2, 0], Radius[0.05] - Filter-> Calculator:
Lift: 升力，计算出压力在y轴方向的投影
Result Array Name: Lift Force
Drag: 阻力，计算出压力在x轴方向的投影
Result Array Name: Drag Force
- FIlter-> IntegrateVariables
- File-> Save Data
勾选Write Time Steps 和 Add Time Step
完成
