Simple boundary conditions

WebbPeriodic boundary conditions Let’s first elaborate on the periodic boundary conditions. For simplicity, we assume that the system is two-dimensional and that the two sides are of equal length, that is, L x = L y. Generalizations to three (or even more) dimensions and for any rectangular or parallelepiped (rhomboid) shape is straightforward.
