All scene elements can be added from RealFlow's “Edit” menu:
- Add > Emitters | Objects | Daemons
RealFlow nodes can be moved, scaled, and rotated with the W, R, and E keys.
Imported objects from SD files have to be unlocked before they can be transformed with Selected object > Node Params > Node > SD ↔ Curve
Viewport perspective is changed with the 1, 2, 3, and 4 keys.
Shading modes are toggled with the 7, 8, 9, and 0 keys.

To create a calm and even surface, please follow these steps:
Start the simulation without the influence of the “k Speed”
...
and "Drag Force" daemons.
- Fill the object until the desired water level has been reached and let the simulation run for a few more frames.
- Set the emitter's “Speed” parameter to 0.
- Create an initial state and activate “Reset To Initial State”; reset the scene.
- Add /Or activate the a “k Speed” daemon.
Set “Limit & Keep” to “Yes”.
- Create two animation keys for “Max speed” with values of 1.0 (frame 0) and 0.01 (frame 200)Node Params > k Speed > Limit & Keep > Yes
- Max speed > 1.0
- Max speed > right-click > Add key
- Shift the timeline slider to frame 200 (the fluid disappears).
- Max speed > 0.01
- Max speed > right-click > Add key
- Reset (the fluid reappears).
- Add a “Drag Force” daemon.
- Under Drag Force > Drag Strength create two keys with values of 0 (f = 0) and 75 (f = 200).
- Simulate. At frame 200 the fluid should be calm and relaxed.
- Create a new initial state for your final simulation (see below)as described above.
...
- Reset.
An initial state can be saved easily:
...
This procedure will help you get an even fluid surface you can use as a starting point for a new simulation. Depending on the number of particles, this process can take a while. We therefore recommend disabling the viewport during simulation (Alt + D) or using the Command Line version:
- Simulation button context menu > Command line
