HardSphere¶

class
HardSphere
: public feasst::ModelTwoBody¶ The potential energy for a hard sphere model of radius \(\sigma\) and separation distance \(r\) is as follows
\( U_{HS} = \left\{ \begin{array}{lr} \infty & r \le \sigma \\ 0 & r > \sigma \end{array} \right. \)
The cutoff model parameter must also be specified, or essentially equated to sigma in order to not skip this HardSphere interaction. For this reason, HardSphere-only models are often used in conjunction with the Configuration argument “set_cutoff_min_to_sigma”.
