Found an interesting string vibration from a model that was generated by specific settings.
Detailed video capture of the model event
User interface with physics engine running the simulation with edges as strings and nodes as charges repelling each others.

Has anyone found more similar events in any other models or by perturbing the models?
By analysing the nodes seems there is 5 nodes that pull the string in a direction and 3 nodes between them that don't create a pull. As seen in the picture below with a closeup of the string.
