Here you can define the conditions for the creation of foam particles based on various threshold parameters.
...
As an alternative, it is possible to create foam from the main fluid body instead of splash particles, but you can use both methods at the same time as well. With “Yes”, the associated parameters become unlocked and you will be able to define various threshold values to control the foam creation process and the areas of foam emission. These areas can be previewed – a description of how to activate this feature is described here.
@ emission rate
With this parameter you can directly define the number of emitted particles per second per cubic metre. It replaces the emitter's “Resolution” parameter.
...
This parameter takes the fluid surface's main direction of motion into account. The particles themselves also have an individual direction of motion caused by their velocity. RealFlow measures the angle between these two directions, and when the angle is between 0° and the given threshold splash particles will be added. The value is measured in degrees [deg].
@ curvature threshold
The core fluid's surface has a certain amount of “roundness”, also called curvature. Particle emission can also be controlled with this value. This parameter is dimensionless and any value greater than or equal to 0 can be used. Higher settings decrease the number of particles, because a stronger curvature is needed for areas where foam is generated.
