Specifies the maximum amount of seconds [s] for the foam particles’ existence. RealFlow calculates a random value between “@min lifetime” and “@max lifetime” to achieve a realistic and randomized vanishing of the foam structures.

Foam min friction
The actual friction value lies between "Foam in friction" and "Foam max friction". The value specifies what amount (in percent) of the grid fluid’s velocity will be transferred to the foam particle. A value of 1.0 means that the entire velocity is transferred and this means that the foam particles are stuck to the grid fluid. A value of 0.0 indicates that the foam particles are not affected by the grid’s fluid’s velocity at all.
Foam max friction
The actual friction value lies between these two values and "Foam in friction" and "Foam max friction". The value specifies what amount (in percent) of the grid fluid’s velocity will be transferred to the foam particle. A value of 1.0 means that the entire velocity is transferred and this means that the foam particles are stuck to the grid fluid. A value of 0.0 indicates that the foam particles are not affected by the grid’s fluid’s velocity at all.
