Zusammenfassung:We illustrate the present state of the art in large-scale atomistic simulations through various direct simulation Monte-Carlo calculations of the Rayleigh-Taylor and Richtmyer-Meshkov instabilities. The results are qualitatively and quantitatively analyzed, and compared with previous Navier-Stokes-based theory and simulations. We find that large particle-based simulations are able to capture both traditional hydrodynamic behavior as well as small-scale atomistic effects.
