Dear LAMMPS users
I am trying to calculate entropy from MD simulation using lammps software. For that, I need to know the angular velocity and principle moment of inertia for each molecules. I am using TIP4P-Ew rigid water model, with atom style full. Is it possible to calculate angular velocity of each molecule or dump the angular velocity using lammps? I looked at the manual and found I need to change atom style from full to body. Do I need to the data file for that?
I also tried to use thus:
"compute cc1 all chunk/atom molecule"
But looks like style "molecules" is not appropriate for my case.
It will be great if someone can assist me on that. Thank you very much.
