There are six different types of fluids and materials - and they are able to interact. All types, except "Dumb", are GPU-accelerated:
- "Dumb” particles are often used for spray or foam. These particles cannot react with each other and do not have the characteristic fluid properties, but they are simulated very fast.
- "Liquid - SPH" is a very accurate fluid solver.
- "Liquid - PBD" is a very fast fluid type (faster than “Liquid - SPH”).
- "Granular" is suitable for substances like sand or snow.
- "Viscous" fluids are suited for substances like caramel, yogurt, oil, or lava.
- "Viscoelastic" is the choice of materials such as rubber, caoutchouc, silicone, or "memory foam".
Not all materials are able to interact. For a complete list of possible interactions please visit → this page.
Resolution
With this setting you can change the amount of particles, . “Resolution” mainly depends on scene scale and emitter scale, but it also affects the fluid’s material's mass and therefore depends on “Density”, too:
- With “Resolution” set to 1.0, a volume of 1 m x 1 m x 1 m filled with contains exactly 1,000 particles.
- The parameter accepts any positive value.

Compute Vorticity
Vorticity hardly contributes to a fluid's behaviour and is therefore channel computation is disabled by default to improve performance. Activate this option before the simulation starts if you need it for → filtering or shading purposes.
