Set the formula(s) SPPARKS uses to compute pairwise energy of interaction between sites or particles in an off-lattice application.
The coefficients associated with a pair style are typically set for each pair of particle types, and are specified by the pair_coeff command.
Here is the list of pair styles defined in SPPARKS. More will be added as new applications are developed. Click on the style to display the formula it computes, arguments specified in the pair_style command, and coefficients specified by the associated pair_coeff command:
