I'm trying analyze the interaction between 2 polymeric nanofibers that are located at a certain distance from each other. The simulation works fine, but for fibers that are located close to each other, I'm observing a welding-like behavior (fibers move towards each other and merge) as simulation continues.
I want to keep these fibers separated at the initial distance at all times. Can I use "fix/recenter" to fix center of masses of polymer chains that are at the surface? Do you have any other suggestions,
