I posted awhile ago about having trouble using dpd. I rebuilt the upgraded version of lammps with all the packages, but when i try to run a simulation with dpd i still get "invalid atom style" the input file is as follows.
# This is LAMMPS input script specifies a simple DPD simulation.
# It reproduces Fig. 2 of Groot and Warren, J. Chem. Phys. 107,
# 4423 (1997)
units lj

# create simulation box

# define masses and interaction coefficient

# create initial velocities

# change neighbor list parameters to avoid dangerous builds

# first equilibrate the initial condition

any help would be greatly appreciated
