This object will be used as an obstacle in the simulation. As with a fluid object,obstacle objects currently should not intersect. As for fluid objects,the actual mesh geometry is used for obstacles. For objects with a volume,make sure that the normals of the obstacle are calculated correctly, and radiating properly(use the Mesh ‣ Normals ‣ Recalculate Outside in mesh edit mode),particularly when using a spinned container.Applying a Subdivision Surface Modifierbefore baking the simulation could also be a good idea if the mesh is not animated.
选项
- 体初始化类型
- 详见 体初始化类型。
- Slip type
确定障碍物表面的粘着性,称为“表面粘附”。表面粘附性取决于流体和表面纹理在真实环境中的摩擦/粘附/吸收特性。
- 无滑移
- 导致流体粘在障碍上(表面相对速度为0)。
- 自由滑移
- 允许沿障碍(仅相对法向速度为0)运动。
- Partial Slip
- 混合这两种类型,0是大多没有滑移情况,1是自由滑动。注意,如果目正在移动,它也将被当做无滑动自动处理。
Example of the different boundary types for a drop falling onto the slanted wall.From left to right: no slip, partial slip 0.3, partial slip 0.7 and free slip.
- 动画网格/导出
- 见 动画网格/导出。
- Amount
- 决定无滑移和自由滑动之间的混合量,如上所述。
- 影响因子
- 对移动物体撞击的增益/损失流体体积的校正。如果对象不动,则该设置没有任何效果。然而,如果它是与流体碰撞的话,负值代表从流体域抽走流体,正值代表增加流体。范围从-2.0至10.0。
