A question about atom_vec_dpd.cpp

Dear all,

I am just confused with atom_vec_dpd.cpp. In this source code, it contains the internal energy and internal temperature. As we know, dpd beads consist of atoms. But how do atoms form into a dpd bead in this source code? Thanks a lot for the help.

Best,
Shiyi

from the perspective of LAMMPS. a DPD bead *is* an atom.
