ExternalDistance #

It depends on the distance between particles and a structure such as a planner surface.

Example #

[[forcefields.external]]
interaction    = "Distance"
potential      = "LennardJonesWall"
shape.name     = "AxisAlignedPlane"
shape.axis     = "X"
shape.position = 0.0
shape.margin   = 0.5
parameters     = [
# ...
]
