The coloring of bonds in various states is as shown in the figures above. I would like to understand the criteria or mechanism for bond generation in the Bonding V2 model.
In Figure 1, the particle within the red circle has formed black bonds with several surrounding particles, indicating established effective connections. However, there is one distinct green bond. My understanding is that this might be because the centroid distance between these two particles exceeds the contact radius, preventing it from turning into a black bond at the designated time.
In Figure 2, not even a green bond is generated between Particle 1 and Particle 2.
Therefore, my question is: Under my setting where the contact radius is N times the particle radius, within what specific distance range does the system generate a green bond? For example, does a green bond initially form within the interval "0 < centroid distance < X × contact radius"? (It is known that when the centroid distance ≤ contact radius, the green bond turns into a black bond at the designated time.) If the distance exceeds this range, no bond is generated at all.
I hope to obtain a specific numerical range or a clear criterion. I need to clarify this mechanism to better interpret my simulation results.
