The Active Bodies feature in Phoenix allows for two-way interaction between scene geometry and the Phoenix simulation.
When an object is selected as an Active Body, the simulation both influences and is influenced by the Active Body's movement. This allows objects such as boats to float over a Phoenix ocean simulation and be affected by its waves, or objects placed on the ground to be washed away by flooding waters.
Objects selected as Active Bodies may also be animated in which case they will follow the animation while also being influenced by the Phoenix simulation. A speedboat simulation is a great example of this mutual interaction in action - the speedboat is heavily affected by the the water while also able to cut through the waves and produce large amounts of foam. You can balance between the influence of the animation and the fluid from an Active Body's Per-Node properties' Original Animation Influence option.
