Dear Steve and all,
I recently tried to use “fix freeze” command to speed up a packing generation process by removing all the kinetic energy from the system (at least this is what the word “freeze” suggests).
Well, that didn’t work out. Because instead of zeroing out all the velocities, fix freeze zeroing out all the forces and torques.
I was just wondering why it was implemented this way. Obviously, this could lead to a very non-physical situation, such as particles penetrating each other.
I would like to suggest zeroing out all the velocities instead of forces and torques.
Correct me if I’m wrong.
