 The interaction between two particles is defined by the types of their systems. This approach makes it easy to support new methods and different physics
 by adding a new system and defining its pairwise interaction wth other systems.

 To illustrate this, \autoref{fig:systems} depicts particles within a simulation domain. The black particles belong to system $\mathcal{S}_1$ and the gray particles belong to system $\mathcal{S}_2$.
 In general, the force $f_a$ experienced by a particle $a$ is calculated as
