This compound applies a directional force that defines an acceleration over time. It moves particle strands based on their existing velocity. Unlike the Gravity Force compound in the Forces group, this compound applies a force to the strands themselves, not the particles.
Plug this compound's Force output into a Force port on the Add Strand Forces compound or into a Forces port on the Strand Dynamics Framework compound.
For more information on using dynamics on strands, see Creating Strand Dynamics [ICE Particle Simulations].
