## Abstract:The influence of different boundary conditions on the density of random packings of disks is studied. Packings are generated using the random sequential adsorption algorithm with three different types of boundary conditions: periodic, open, and wall. It is found that the finite size effects are smallest for periodic boundary conditions, as expected. On the other hand, in the case of open and wall boundaries it is possible to introduce an effective packing size and a constant correction term to significantly im… Show more

“…It has been shown for RSA of disks that the measured value of saturated packing fraction for small packings os-cillates with respect to the system size, similar to the oscillations found in the tail of the autocorrelation function [25]. Therefore, it was expected (as a packing side length used in the study is much larger than 5) that the finite-size effects should not affect obtained values of packing fraction.…”

“…There are additional maximas for particles with non-equivalent faces, such as truncated tetrahedron. According to [35], G(r) is strictly connected with an error in packing fraction introduced by finite size effects, so, as there are almost no correlations after r = 5, finite size effects should be negligible for a packing size used in this study. In order to measure full orientational order propagation, the order parameters conforming to polyhedral groups of point symmetries were used:…”

“…Typically, the length of this line segment was L = 10 6 , but for spherocylinders and dimers different sizes: L ∈ [10 2 , 10 7 ] were also used. Periodic boundary conditions were used to minimize finite-size effects [25]. Each shape had a unit surface area.…”
