Connectivity_radius selection

[songjiazheng1]

Hello, I am currently working this GNS project with my dataset. But I have some trouble. I want to konw to select a suitable default_connectivity_radius. I noticed that in WaterDropSample the radius had been set with 0.015. But I can't understand why select this value? Is this radius related to the inter-particle distance in the dataset.
Could you please guide me on how to choose the radius? Any additional instructions or alternative links would be greatly appreciated.Thank you for your assistance!

We typically aim to have ~10 particles (GNS nodes) along the connectivity diameter. That's how it is chosen.
