A sloshing fluid and its relaxed state created with the method described here.
Please 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.
The Relaxation Process
To create a calm and even surface, please follow these steps:
Start the simulation without the influence of the “k Speed” daemon.
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 “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)
Simulate. At frame 200 the fluid should be calm and relaxed.
Create a new initial state for your final simulation (see below).
An initial state can be created saved easily:
- Make an initial state with the “Make Initial State” button Node Params > Initial State > Make Initial State.
- Set “Use Initial State” to “Yes”.
- Activate the “Reset To InitialState” option with a click on the triangle next to the “Reset” button.
- Optional: backup your previous data or apply a new export name for the emitter.
- Reset the scene to load the initial state at frame 0 (or any other specified frame).
- Simulate, using the initial state.
