This panel allows you to describe the characteristics of the foam particles which are created when the bubbles reach the fluid's surface. The settings are exactly the same as with RealFlow's “Foam” emitter.
Surface offset
Foam particles are created from the core fluid's surface and with this parameter you can control how far away from the surface the particles will be placed. This parameter becomes interesting when you want to mesh the foam and waterline particles, because it can help to avoid flickering. "Surface offset" is given metres [m].

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.

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.
