流体障碍

参考

面板:物理 ‣ 流体 类型:障碍

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 Modifier before 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.

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。
