Does anyone have a DPD input script that i could use as a template or a how to tutorial on setting up problems with DPD? I'm trying to alter the couette flow input script to use DPD as it's force fields, but when i set the atom_style to dpd i get an error that says i've picked an invalid atom style. I have the latest version of lammps installed so i have no idea what the problem is.

thanks,

Are you sure you built lammps with the dpd package? It is not included by
default. You could try "make clean; make yes-dpd" and rebuild lammps,
maybe that fixes your problem.

Hope this helps,

Use atom_style dpd. The DPD ff requires velocities for
ghost atoms be communicated.
