An initial state is a starting point for a new simulation. A typical example is a glass of water:
- In the first step, the glass has to be filled with particles.
- Then, the fluid needs some time to relax and calm down.
- Finally, the calmed water can be used for the main simulation, e.g. for ice cubes falling into the glass.
Here is how to achieve this:
- Pour particles into a glass and stop the simulation (step 2 in the list above) when the fluid is calm.
- Then press the “Make Initial State” button in the node's "Node Params" panel (A).
- Set “Use Initial State” to “Yes”.
- Activate the “Reset To InitialState” option next to the “Reset” button. (B)
- Reset the scene. The initial state will be loaded on the first simulation frame.
- Simulate again, but this time with the ice cubes.

RealFlow writes out a single file to the project's "initial state" folder. Initial states can be created from any simulation node: Dyverso and Hybrido nodes, standard particle emitters, rigid and soft bodies, MultiJoints, and RealWave meshes.
