Set noise field Daemon
The Noise daemon (Realflow>daemons>noise Field) gives realism to the simulation by adding a random force field. This daemon can be used to randomly disturb particles inside the fluid simulation, and consequently achieve a realistic simulation. Adjust Strength to 5 and Noise Space Scale to 2.
This next step is optional, but additionally you can deactivate the Visible in Editor traffic light (turning it into a red colour) so that we can have a clean vision of the system.
