[lammps-users] atom_style dpd

Hi all.

I understand that atom_style dpd updates the velocities of ghost particles at every timestep.

Just wondering what the behavior is for plain old atom_style atomic? Are ghost velocities set to zero or just updated less frequently than every timestep? Thought maybe someone would know off-hand.

Thanks,
Craig

Aside from atom_style granular and dpd, the others
do not store or update velocities on ghost atoms, so
they're undefined.

They're only needed if the pair potential is a function
of vi and vj, which is normally not the case.
