Currently required in order to calculate normal and curvature of particles. Link any fluid dynamics node here.

Calculates and attached a surface normal property.

Calculates and attaches a curvature property.

Calculates and attaches a particle anisotropy property. If you don't use a thin sheet that calculates anisotropy, you can use this one in order to use it in the anisotropic mesher (or for any other purpose).

To find particles nearby this radius defines the maximum distance around each particle to find neighboring particles.

Defines the minimum density a particle must have to be included.

Defines the maximum density a particle must have to be included.
