Smoothed Dissipative Particle Dynamics #1184
Smoothed dissipative particle dynamics package. Adds pair sdpd/taitwater/isothermal for isothermal SDPD simulations of water. Also adds fix meso/move to move SPH/SDPD particles with prescribed velocities and fix rigid/meso to constrain clusters of SPH/SDPD particles to move as rigid bodies.
Ensembles of simulations measuring translational and rotational diffusion coefficients of sphere were performed and the results agrees with the theory. Also velocity and angular velocity autocorrelation functions showed power-law decay behaviour (with correct exponent) agreeing with theories that take hydrodynamic interactions into account. Results of tests will be published in a future paper.
No other feature of LAMMPS will be affected.
