and adjust the now unlocked threshold values. These parameters are exactly the same as in the “Splash” emitter's “Splash Creation” panel. Once you have found a working combination, all you have to do is to transfer the values from the domain to the emitter and start the simulation. This is a very fast way of getting an idea of where splashes will occur, but without having to run the entire splash pass. For a complete description of this workflow, please visit this page.
Emission rate
When you take a look at the emitter's “Particles” panel you will see that it lacks a “Resolution” parameter, because “Emission rate” is used to create particles. The value you enter here is the number of particles which are created per second per cubic metre.

You can use the fluid's curvature to trigger the generation of splash particles. This value represents the minimum curvature for the creation of splashes. Curvature can also be seen as the fluid surface's “roundness”. With higher values, the fluid's borders/surface must have a stronger curvature to start the emission of splashes. With small values, the parameter is less sensitive and creates particles even in areas with low curvature. Any positive value This parameter is dimensionless and any value greater than or equal to 0 can be used.
Speed threshold
It is also possible to use the underlying grid fluid speed for the splash creation process. If the fluid's velocity is below the adjusted threshold, no new splashes will be generated. “Speed threshold” is very easy and effective way to reduce the amount of splash particles. The parameter's unit is metres per second [m/s].
