Figure 8From: GPU-enabled particle-particle particle-tree scheme for simulating dense stellar cluster system Number of interactions for all particles per unit time as a function of N . For all runs, we use \(\Delta r_{\mathrm{buff}} =3\sigma \Delta t_{\mathrm{soft}}\), \(\eta=0.1\), \(\Delta t_{\max} =\Delta t_{\mathrm{soft}}/4\) and \(\Delta t_{\mathrm{soft}} = (1/256) (N/16\mathrm{K})^{-1/3}\).Back to article page
