Dear all
I am trying to learn LAMMPS now and use it to calculate the tensile property of carbon nanotubes. I build a finite length tube, fix the atoms at one end and set a constant velocity on the atoms of the other end. one thing I wish to get is the force-time curve.
My question is that which command I can use to computer the resultant force on each fixed atom? I read the help documents and the ‘compute’ command but fail to find the answer. Would you please help me on it?
Thanks.
