Particle Fluid from Object
Creates a Particle Fluid Object from SOP Geometry.
This tool converts your object into a cluster of particles, and is similar to Liquid from Object; however, this tool is particle based not volume based. Particle fluid is useful, for example, to simulate water dripping, as it is able to simulate splashes.
Using Particle Fluid from Object
Click the
Particle Fluid from Object button on the Fluids tab.Select the geometry object to convert to particle fluid and press Enter to confirm your selection.
You can modify the Particle Separation in the parameter editor to control the distance between particles. A smaller particle separation will result in a greater number of particles and a higher resolution.
For specific parameter help see the 
Particle Fluid Object node help.
