Dear all,

I found that compute RDF did not work with dynamic group. Is this a bug in LAMMPS? Or does anyone konw how to get the RDF of the atoms in a specific region. Thanks.

Regards,

Ethan

the problem is already at the conceptual level. you are trying to do
an ill-defined computation.

for example, for any pair of atoms, which should contribute to the
RDF? where both atoms are inside the region? or either? or only the
center?
also, how would you compute the normalization for such a system?
