GF::External

The external force allows you to inject any kind of directional force into the dynamics system.
This force is a grid force, so it acts on the velocity (grid) motion field of the dynamics nodes and emits direction vectors (while the strength of the force is the length of that vector) into it.
If you want to create wind or move things in a certain direction you can use this force for it.
