Fluid Inflow / Outflow

To control the volume of the fluid simulation, you can set objects in the scene to add or absorb fluid within the Fluid Domain.

Inflow

Reference

Panel:Physics ‣ Fluid
Type:Inflow

Fluid Inflow settings.

Volume Initialization Type
See Volume Initialization Type.

This object will put fluid into the simulation, like a water tap.

Inflow Velocity
Speed of the fluid that is created inside of the object.
Local Coordinates/Enable
Use local coordinates for the inflow. This is useful if the inflow object is moving or rotating, as the inflow stream will follow/copy that motion. If disabled, the inflow location and direction do not change.

Outflow

Type:Outflow

Fluid Outflow settings.

Any fluid that enters the region of this object will be deleted (think of a drain or a black hole). This can be useful in combination with an inflow to prevent the whole domain from filling up. When enabled, this is like a tornado (waterspout) or „wet vac“ vacuum cleaner, and the part where the fluid disappears will follow the object as it moves around.
