Dear lammps users
I am a group of atoms as a rigid body that is being pulled out from another polymer material. I want to calculate net force (fx fy and fz) on this group of atoms. Which command is most suitable for this? Please advise.
I am using like this
compute frc BN property/atom fx fy fx
compute forc BN reduce sum c_frc c_frc c_frc
Is it right? I mean will it take all the three force components fx fy and fz on each atom ?
