This type represents the standard “watery” substances, but is also used for viscous fluids RealFlow's liquids are perfectly suited to all kinds of projects with a demand for high detail.

 

Type

This parameter is only available for → “Splash”, → “Splash & Foam”, → “Wet”, → “Wet & Foam”. Here are your options:

  • → “Dumb” particles are simulated very fast, cannot react with each other and will not be affected by other emitters.
  • → “Standard - Liquid - Particles” is used for all watery or high-viscous substances. Simulations with this type take much longer, but they also create very realistic results.
  • → “Liquid - Hybrido” offers a good balance between simulation speed and quality. They are controlled by RealFlow's Hybrido solver and therefore have a “Cell size” parameter.
Density

This parameter is defined as mass per volume unit and is different for each substance. “Density” is only relevant for interacting fluids with different properties, e.g. water and oil, or water and foam. With single emitters, changes have no effect. The unit is kilograms per cubic metre.

Viscosity

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. High settings (40-50 and higher) can lead to misbehaving particles.

Surface tension

A fluid's tendency to contract and create drops and tendrils is increased with higher settings. Very high values (100+) might lead to instabilities – especially in conjunction with high viscosity.

Max Particles

Please enter a value to stop emission at a certain amount of particles. "Max particles" is based on the total amount of emitted particles. Let's say you have entered "50,000". If there are currently 1,000 particles in your scene, but you have already deleted 49,000 particles RealFlow will stop the emission.
