What do you mean by mutually inconsistent? From what I understand, they aren't. Also, [bonds] type 6 won't work for what I want, since I don't want to keep the molecules at a fixed distance but to prevent them from coming closer, i.e. I want a potential that depends on the distance between the

Gromacs users, I have a small test system of about 2500 atoms which consists on a few organic molecules in a box of water. I'm trying to use distance restraints to keep each molecule apart from each other and I've failed until now. I'll start by saying that the simulation runs smoothly without
