[lammps-users] dump command in DPD simulation

Steve:

Thanks very much.

My question is not why the dump files for dump “all” and dump “polymer” are the same. I know the “polymer” is the “all” in my simulation.

The question is why I observed the phase separation in the dump files for dump ”segment1" and dump " segment2", but not in the dump files for dump “all” or dump “polymer”.

In my understanding, the atoms in dump files for dump “all” or dump “polymer” are composed of the atoms in the dump files for dump “segment1” and dump " segment2".

Please refer to the attached pictures.

Still not sure if you asking a LAMMPS question
or a viz question about why VMD made the pictures
it did. Are you saying there are different atoms
in the dump files that you expect? If so, look
at the group counts that LAMMPS output and see
what the discrepancy is.
