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 results with high viscosity. Try Liquid - PBD 20 | 20 or Liquid - SPH 200 | 200
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.
