"In other cases, if the **box size is too large**, particles must cover greater distances, resulting in smaller final displacements. This reduces the impact of insufficient halo size on boundary artifacts. \n",
"\n",
"### Explanation\n",
"\n",
"- **Large Box Sizes**: In larger simulation boxes, particles tend to have smaller relative displacements (or slower speeds). This reduces the frequency of interactions with particles in neighboring subdomains, making boundary artifacts less pronounced, even if the halo size is smaller.\n",
"\n",
"- **Smaller Box Sizes**: In smaller boxes, particles cover a greater relative distance, leading to more frequent interactions with boundary particles. Here, the halo size must be carefully chosen to capture these interactions accurately, reducing visible artifacts in the visualization.\n",
"\n",
"\n",
"In this scenario, we can see that the insufficient halo size does not lead to severe artifacts, as particles are less affected by neighboring boundaries.\n"
