Here is the place to control the foam particles' lifetime and behaviour.

 

Surface offset

With 0.0, particles are created directly at the fluid's surface, but you can also define an offset between the core fluid and the splashes. This distance is measured in metres.

Stringiness

If you can see filaments and regular foam patterns please decrease this parameter. “Stringiness” ranges ranges between 0.0 and 1.0; 0.0 can help to suppress the filament effect.

Foam min lifetime

If you want to destroy the particles after a certain time then you can define a lifespan with “Foam min | max lifetime”. The actual lifetime will be somewhere between both values, and this value defines the lower limit. The value is given seconds.

Foam max lifetime

If you want to destroy the particles after a certain time then you can define a lifespan with “Foam min | max lifetime”. The actual lifetime will be somewhere between both values, and this value defines the upper limit. The value is given seconds.

Foam min friction

This value specifies the minimum amount of the grid fluid’s velocity that will be transferred to the foam particle. 1.0 means that the entire velocity is transferred and the foam particles are stuck to the grid fluid. With 0.0 the foam particles are not affected. If you use different values for the min and max parameters the actual friction will be somewhere between both settings.

Foam max friction

This value specifies the maximum amount of the grid fluid’s velocity that will be transferred to the foam particle. 1.0 means that the entire velocity is transferred and the foam particles are stuck to the grid fluid. With 0.0 the foam particles are not affected. If you use different values for the min and max parameters the actual friction will be somewhere between both settings.
