Splashes occur, for example, when waves break or collide with objects. When the particles pass the HyFLIP fluid's surface they are destroyed. RealFlow's “HY_Splash” emitters are splash emitter is able to interact with most of the available daemons.
Quick Start
Starting point for splashes is always an existing HyFLIP simulation:
- Set the domain's simulation state to → “Cache” (“yellow rocket”).
- Add a "Splash" emitter from the “Hybrido” shelf.
- Reset the scene.
What you can see now is a bounding box with a dimension of 10 m x 10 m x 10 m. The domain can be positioned and scaled with the settings under Node Params > Node or the W and R keys. You can prevent the particles from leaving the domain:
- add a → "k Volume” daemon and adjust it to the splash domain with the R key
- or make sure that the splash particles will be enclosed inside a container or a cube.
You can control the emission of particles with the parameters under → “Splash Creation”:
- A wide variety of threshold values are used to control in which parts of the HyFLIP fluid splashes will occur. These areas can be → previewed.
- The higher the thresholds, the less particles you will get ("@ angle threshold" is the only exception).
- The “Emission rate” parameter is also responsible for the number of particles. It can be necessary to use very high values of 1 million and more.
