[lammps-users] dipole

Dear,

I have two question about dipole simulation.

I want to keep the position, velocity, orientation, and angular velocity of one group of atoms is zero when doing simulation. can the fix setforce command zero orientation and angular velocity ? Manual only say we can zero their force, but not say about moment and torsion.

the other question is which software can read in lammps’ dump file and view direction of dipole moment of atoms.

Thanks very much

If you don't put those atoms in the group being time integrated, then
those quantities won't change.

Re: viz - Pizza.py has some options to viz dipolar particles (as 2
nearly overlapping
spheres).
