Like “Splash”, the “Foam” emitter has its own domain represented by a box when “Bounded” is set to “Yes”. Foam must be linked to a domain in order to become created and any splash, attached to the domain, will generate foam – as long as “From splash” is set to “Yes”. Foam particles are only generated within this domain, but can escape from it. Multiple foam domains can be added and placed inside the grid fluid domain, and computed on different machines at the same time with the help of RealFlow's IDOCs. Foam particles cannot interact with daemons, because they are controlled directly by the HyFLIP solver, . Please also bear in mind that they are always simulated as “Dumb” particles. Hence the “Foam” emitter has a drastically reduced “Particles” panel and all relevant physical properties are calculated internally.
