If you want to experiment with different strength values please be careful. Since gravity is an accelerating force, it strongly affects the behaviour of fluids. It is possible to create “denser” fluids with higher values or to avoid exaggerated splashes, but changes cause the fluid to behave completely differently.

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. Forces take a little time to display their full influence. This means that they accelerate the particles over a certain time span depending on their strength. High forces exert stronger accelerations and the particles or bodies become faster and faster as long as the force acts on them. The result is a curved stream of particles.

This is the dimension of the gravitational acceleration and it depends on your current location. Please read the annotations above to get a better understanding of RealFlow’s "Gravity" daemon. “Strength” does not accept negative values. If you want to change direction of the force, you have to rotate the daemon“Strength" accepts both positive and negative values. The "Strength" parameter is also known as “g” and is different for any location, because it strongly depends on a body’s mass. Even here on Earth, gravitational acceleration differs from place to place. Hence the given values are only averages.:
