Model details please see the attachment. In the model, boundaries 1, 2, 3 and 4 are four internal extra-added boundaries. As running goes on, the small circle become large, However, at some time, the terminal points of boundaries 1, 2, 3, and 4 no longer contact with the small circle but come into the small circle, you can see this in the Result Plot. Why? How to make the terminal points of boundaries 1, 2, 3, and 4 always be on the small circle.
