- It is possible to attach multiple emitters to one common "Fluid" container under "Simulation". In this case, all emitters will share the same properties adjusted here.
- If you want to simulate fluids with different properties, e.g. old and water, and make them interact you have to use two individual domains.
Type
There are three different fluid types available:
...
With this setting you can change the amount of particles. When “Resolution” is set to 1.0, a volume of 100 cm x 100 cm x 100 cm is filled with 1,000 particles. The parameter accepts any positive value.
...
“Int Pressure” simulates the forces between nearby particles and pushes them apart - this makes the fluid fill a greater volume. This parameter has no effect on is not available for "Dumb" particles.
Ext Pressure
“Ext Pressure tries to limit a fluid’s expansion tendency and can be compared to atmospheric pressure. This parameter has no effect on is not available for "Dumb" particles.
Viscosity
...
- The default value of 3.0 describes the viscosity of water.
- If the fluid does not behave correctly with higher settings (around 50+) you should consider increasing substeps under Scene > Solver.
- Equal values for "MIN | MAX Substeps" produce the best results with highly viscous fluids. Try Liquid - PBD 20 | 20 or Liquid - SPH 200 | 200
This parameter has no effect on is not available for "Dumb" particles.
Surface tension
A fluid's tendency to contract and create drops and tendrils is increased with higher settings. You can enter any value between 0 and 10. This parameter has no effect on is not available for "Dumb" particles.
