2D Lennard-Jones Potential
constraint LJPotential2D (1) [2] [3] # (1) int, unique constraint tag # [2] double, spacing, default: 1.0 # [3] double, alpha, default: 1.0
This constraint implements the Lennard-Jones potential for 2D systems, viz.,
where rrr is the distance between two particles, σ\sigmaσ is the size of particle, which is taken as one tenth of spacing [2].

The force is computed as
