This is often used with an object that has been converted to points. You can either store data on the points or instance geometry. Embed in Fluid is usually used for tracking fluid flow passively, by using marker particles.
This tool only works with volume based fluid.
Using Embed in Fluid
-
Create a geometry object and source within a container.
For more information on containers see: Smoke Container, Flamefront Container, and Liquid Container.
-
Click the Embed in Fluid tool on the Volume Fluids tab.
-
Select the object to embed in fluid and press Enter to confirm your selection.
This example shows a grid that has been converted to points embedded in the fluid to track the flow.
Tip
Increase the Feedback Scale parameter on the Internal Forces tab of the Fluid Solver when using fluid to push a rigid body object.
