#### Particle Group

The particle group to calculate the properties for.

#### Particles

The particle type of the Particle Group to use.
Passive
Vorticity
Liquid
Diffuse

#### Fluid Dynamics (Boundary)

Link a fluid dynamics node in order to get the domain boundary being taken into account for any simulation particles.

#### Duration

Takes a duration node in order to control when of the weak spring operation is evaluated.

#### Iterations

#### Particle Spacing

#### Spring stiffness

The spring stiffness. Be careful with this. The lower the time step (or rather the more substeps) the higher you can set the stiffness without it getting unstable.
