(you’ll need to set the referenced assembly location of KangarooSolver.dll when you open it - usually this will be in
C:\Program Files\Rhino 6\Plug-ins\Grasshopper\Components
if you are on 6, or
C:\Program Files\Rhino WIP\Plug-ins\Grasshopper\Components
if you are using the WIP)
You can make it negative for repulsion or positive for attraction.
The exponent controls how quickly the force falls off with distance.
