Smoothed Dissipative Particle Dynamics package for LAMMPS

SDPD is useful for hydrodynamics simulations at mesoscale where the effect of thermal fluctuations are important, but a molecular dynamics simulation is prohibitively expensive. We have used this package to simulate diffusion of spherical colloids.

The results (particularly the long-time behaviour of velocity autocorrelation function) are in agreement with theoretical models that take hydrodynamic interactions into account.
