It’s been a while since I needed to restrain anything. However, there is one option to “freeze” things and there are other options to “restrain” tings. If you put a restraint on some movement there were also the option to specify the energy associated with the restraint. This way, you should be able to put a restraint on the things you need and set the associate energy at a level that still allows movement.

As far as I understand, adding atom restraints freezes each atom, and that doesn’t allow movement anymore. How could the above problem be solved?
