Daemons - Surface Tension

"Surface Tension" can only be applied to particle-based fluids. It is a cohesive force acting on the fluid’s skin. You might have noticed that standard emitters also have a setting for "Surface Tension" and basically there is no difference between the property and the daemon. The daemon can be used in conjunction with the emitter value and acts globally on all fluid particles, regardless from their origin. Additionally the daemon has another option that prevents a fluid from breaking apart into smaller drops. This function is called “Balanced”.

"Surface Tension" enhances a fluid’s tendency to accumulate, very similar to viscosity. It can be used to create spherical drops or the typical dripping effect you can observe with faucets. This daemon is also suited for obtaining mercury-like effects. In the viewport the surface tension daemon is represented by two discs with different sizes. Since it is a global force, scale changes will not have any effect on the daemon.

With very high settings you can often observe highly accelerated particles. These fast particles can significantly slow down a simulation and we recommend to use a "k Volume" daemon to delete them and to increase "MIN substeps" and (if necessary) also "MAX substeps” in the “Master” section of the "Simulation Options" panel.





This value defines the overall strength of the daemon’s force. All negative and positive settings are valid.


You can choose between “Yes” and “No”. With “Yes” the daemon’s force field is more homogenous and better spread over the entire fluid. It prevents fluids from breaking apart into smaller drops too fast.
