Dear Lammps users,
Is there a way to measure the force required to hold atoms in a dynamics simulation?
Let's take a nanotube cantilever for example. When the nanotube is deformed, either stretching or bending, there must be a force exerted on the fixed end to hold it there. Then can we know how large the force is?
I usually use fix/setforce 0 0 0 to hold atoms in simulation. However, by doing this, reaction force cannot be measured as Lammps zeros out the forces.
Can anyone help me out?
Thanks a lot,
