Dear Lammps users:
For ‘fix wall/region’, it will calculate the distance of an atom to the wall. However, for an atom which goes across the Periodic boundary and with nonzero image flag, (e.g. 1 0 0), will its distance to the wall be calculated based on the Re-mapped coordinates (i.e. xyz in simulation box) OR based on its unwrapped coordinates (i.e. true xyz)?
Moreover, if the distance is NOT calculated based on unwrapped coordinates, is there a way to make it do so?
