HySPH - Particles (Dumb)

“Dumb” particles can be simulated very fast, because they do not obey the rules of fluid dynamics. This means there are no forces acting between the particles and particle-particle or particle-object collisions are performed on a very low level. In combination with Hybrido, the dumb splash particles simply inherit velocity and direction of the “emitting” grid fluid particles. External forces, for example from daemons, will then decelerate the particles and direct them in a different direction. The possibilities of adjusting these particles are therefore limited.

Type

If you do not want to use the “Dumb” type you can also switch to “Liquid”. Simulations with liquid particles take much longer, but they also create very realistic results, especially for mid-scale simulations.

Density

A fluid's “Density” value does not influence the simulation and you can use any value. This changes when there is more than one particle fluid source and you want to achieve a certain effect, for example fluids that cannot mix, like water and alcohol. The parameter's unit is kg per cubic metre [kg/m³].

Max particles

This parameter is a very convenient method to control the number of particles, although it is rarely used. When the total number of emitted particles exceeds this value, the emitter will not be able to create more particles and emission stops.
