This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract Long-range hydrodynamic interactions have been implemented into the open-source molecular dynamics package, LAMMPS, though the creation of a fix, lb_fluid. These interactions are treated by interpolating the MD particle density onto a discrete lattice, which is then coupled to the fluid. A thermal lattice-Boltzmann algorithm is used to model the fluid, which includes mass and momentum conserving noise, providing a thermostat for both the particles and the fluid. Title of program: fix_lb_fluid Catalogue Id: AEPH_v1_0 Nature of problem The inclusion of long-range hydrodynamic effects into molecular dynamics simulations requires the presence of an explicit solvent. Currently, the only option for incorporating such a solvent into a LAMMPS [1] simulation is the explicit inclusion of each of the individual solvent molecules. This is obviously quite computationally intensive, and for large system sizes can quickly become impractical.
