The Smith and Nezbeda associated fluid model [1] consists of a hard sphere that has an attractive square well patch. The potential is given by (Eq. 1)


\Phi({\mathbf r}_{ij})  =\Phi_{HS}({\mathbf r}_{ij}) + \Phi_{CS}({\mathbf r}_{ij}) + \Phi_{SC}({\mathbf r}_{ij})


where (Eq. 2)


\Phi_{CS} \left({\mathbf r}_{ij} \right) = 
\left\{ \begin{array}{ccc}
0 & ; & r_{CS} < 0.5 \\
- \epsilon & ; & 0.5 \le r_{CS} < \lambda \\
0         & ; & \lambda \le r_{CS} \end{array} \right.
