Hi,
For a DPD simulation, it is a common practice to use constant spring force between atoms to create a larger size of particles. This force supposed to contribute to the equation of motion. But in the lammps documentation in pair style DPD, I found that the contribution of these forces is missing https://lammps.sandia.gov/doc/pair_dpd.html. Is there any command to include that forces DPD simulation?
