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.

Substances with very high viscosity are honey, tar or syrup, for example. Fluids with low viscosity are alcohol, many solvents or liquid gases. The default value of 3.0 describes the viscosity of water. You can enter any positive value and 0.
Compute Vorticity
Vorticity hardly contributes to a fluid's behaviour and is therefore channel computation is disabled by default to improve speedperformance. Activate this option before the the simulation starts if you need it for → filtering or or shading purposes.
