This is the button to create and save the initial state file which will be used to resume the simulation exactly from this moment. To use an initial state with a simulation it is not enough to activate “Use InitialState” – you also have to reset to this specific point. This can be done by tagging the “Reset To InitialState” option next to the "Reset" button. With the next reset, RealFlow will load the initial state file and the simulation starts from 0 again. Existing BIN files will be overwritten with a new simulation, but normally it is not necessary to backup previously generated files. If you need them, do not forget to apply a new name for the emitter, for example.
Here is the workflow:
- Make an initial state with the “Make Initial State” button.
- Set “Use Initial State” to “Yes”.
- Activate the “Reset To InitialState” option 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.
