Overview

...

The Active Bodies Solver node is used to specify the scene geometry which will partake in the Active Bodies simulation. By default, all geometries in the scene are Solid and act as obstacles to the Phoenix fluid simulation. Active Bodies go one step further and can be pushed by the fluid or can float over the liquid surface, unlike Solid obstacles which stay in place and obstruct the movement of the fluid. Additionally, just like the movement Solid bodies can be animated, the movement of the Active Bodies can be animated, so that an Active Body both follows a trajectory, and also gets influenced by the fluid's movement. You can balance between the influence of the animation and the fluid from an Active Body's right click properties' Original Animation Influence option.

Note that mutual  When an object is selected as an Active Body, the simulation both influences and is influenced by the Active Body's movement. Mutual interaction between the Active Bodies themselves is not supported yet. Interaction Also, interaction between Active Bodies and the Phoenix FD Fire/Smoke Simulator is still not supported.

The Active Bodies Solver also node sets up global simulation parameters which affect all Active Body objects in the Interaction list, in contrast to the Phoenix FD Per-Node Properties which are unique for each Active Body. This way you can have several Active Body Solver nodes, each with their own set of Active Bodies with different rigid body behavior for each set.
