Removes fluid particles that flow inside of a bounding box from a simulation.
This tool can be used, for example, to simulate a drain.
Using Sink Particle Fluid
Select the particle fluid to apply the sink to.
Click the
Sink Particle Fluid tool on the Particle Fluids tab.
You can use the handles to drag the purple bounding box around the viewport. Any particle fluid that enters the bounding box is removed.
This example shows half of a particle fluid stream entering a Sink Particle Fluid bounding box. Only the particle fluid that enters the bounding box is removed.
Note
If you want to use a geometry object as a particle fluid sink, instead of a bounding box, use the 
Sink from Objects tool.
For specific parameter help see the Particle Fluid Sink node help.
