  • We discuss hybrid atomistic-continuum methods for multiscale hydrodynamic applications. Both dense-fluid and dilute-gas formulations are considered. The choice of coupling method and its relation to the fluid physics as well as the need for timescale decoupling is highlighted. In particular, by relating the molecular integration timestep to the CFL timestep, we show that compressibility is important in determining the choice of a coupling method. Appropriate coupling techniques for various flow… CONTINUE READING
