ExcludedVolume

ExcludedVolumeWallPotential #

It is a excluded volume potential between particle and a spatial structure.

\[U(r) = \epsilon\left(\frac{r_0}{r}\right)^{12}\]

Example #

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

epsilon     = 0.5
parameters  = [
    {index = 0, radius = 1.0},
    # ...
]

Input Reference #

  • epsilon: Floating
    • It determines the strength of the potential.
  • radius: Floating
    • It determines the effective radius of the particle.
