Figure 7From: GPU-enabled particle-particle particle-tree scheme for simulating dense stellar cluster system Number of steps of non-isolated particles as functions of N (top) and \(\pmb{r_{\mathrm{cut}}}\) (bottom). Bottom panel shows the result of the runs with \(N=128\)k. For all runs, we chose \(\eta=0.1\), \(\Delta r_{\mathrm{buff}}=3\sigma \Delta t_{\mathrm{soft}}\) and \(\Delta t_{\max}=\Delta t_{\mathrm{soft}}/4\).Back to article page
