This value takes the grid fluid particles' speed into account. Particles with a speed smaller than the given value will be not be able to create foam. With 0.0, all particles can contribute to this process. Velocities are measured in metres per second [m/s].
@ vorticity threshold
Here, the grid fluid particles' vorticity is analysed. When the current vorticity is greater than the given value, the particle produces foam.

Foam particles are always created within a certain distance around a source particle. With this parameter you can adjust this distance to avoid unwanted patterns. Higher values also increase the number of particles. This value uses metres [m].
