The "Attractor" is also one of most commonly used daemons and perfectly suited to sculpt and shape fluids, enhance splashes, or create the famous “liquid dance” simulations, where particles are attracted and repulsed to create a dynamic and balanced movement. This daemon attracts particles towards its centre – negative values create a repulsion. Near the centre attraction forces become stronger and particles – or objects – experience greater acceleration. But not only fluids are affected by attractors, because this type can also act on rigid and soft bodies. Bodies with higher masses require higher “Internal force” settings. Another feature is that the "Attractor" daemon can adopt different shapes and its influence can be restricted with a bounding option. Animated "Attractors" are useable for many creative fluid sculpting approaches.

Affect

Particles can be affected in two ways: either by “Force” or “Velocity”. The first option applies an external force, resulting in an acceleration, while the second one only modifies the velocities of the particles without introducing an additional acceleration.
