- 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, → water and foam) and make them interact you have to use two individual domainsfluid container.
Type
There are three different fluid types available:
...
“Int Pressure” simulates the forces between nearby particles and pushes them apart - this makes the fluid fill a greater volume. This parameter 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 This parameter is not available for "Dumb" particles.
Viscosity
Substances with very high viscosity are honey, tar or syrup, for example. Fluids with low viscosity are alcohol, many solvents or liquid gases. You can enter any positive value:
- 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 good results with highly viscous fluids. Try Liquid - PBD 20 | 20 or Liquid - SPH 200 | 200
This parameter 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 This parameter is not available for "Dumb" particles.
Use Initial State
Initial states can be created and activated/deactivated individually for each node (also see → "Initial States"). When
- enabled the initial state will be used
- disabled the initial state will be deactivated temporarily.
