HI Jose and the community!
Just for the reference of users with the same problem in the future, I tried all the methods that Jose mentioned in his reply.
1. The signed distance fields did not show much effect. I suppose it is because my rings are too small.
2. I did manage to find the closest particles, added external forces and directly modified the velocities of the closest 2 particles. The rope would still penetrate if moving fast. Then I tried to directly modify the position to force the closest particles to be aligned with the normal of the ring. This resulted in some unpredicted behaviours where the rope section close to the ring jumps around sometimes.
3. Eventually I decided to just use 24 capsules to form a ring and that worked quite well. It did increase the thickness of the ring significantly tho, whoever wants to do the same trick should also take this into consideration.
Many thanks again!
