This parameter indicates the magnitude of the initial velocity of the fluid and is measured in metres per second [ m/s ]. The direction of the initial velocity can be controlled by simply rotating the emitter node in the viewport. An arrow in the centre of the emitter’s symbol indicates the direction.

The Hybrido fluid's surface plays a very important role with Hybrido simulations, because it is responsible for the creation of the secondary effects as well as the quality of the mesh. The particles inside the cells also contribute to these features. With this parameter it is possible to adjust the number of surface particles within the given "Surface bandwidth" – independent from the main body of fluid. The total number of particles per cell is calculated with the following formula:
Number of particles per cell = Surface particle sampling 3

Analogue to “Surface particle sampling” the main fluid body can be adjusted as well. With this parameter you determine the number of particles of a cell outside the “Surface bandwidth”. These particles are considered "core" particles. The formula is exactly the same as above:
Number of particles per cell = Core particle sampling 3
