Hello every body,
In my system, there is a cylinder constraint, I assumed a circular ring in the middle of this cylinder, then I put one end of 40 polyelectrolytes on this ring (their distances are equal between each two end of the nearest polymers in the ring), the radius of this ring is 25 and the length of each polymer is 100, the problem is that suddenly the energy of the system extraordinary increases (8e40) and it is mostly because of the lj interactions between polyelectrolytes with each other and between polyelectrolytes and the constraint, after warm_up this energy decreases to(5.7e27), but it is still very high and makes my simulation unphysical, I don't know how to control this high energy and make it lower.
I would appreciate if anyone can help me?
