We present a novel multiscale approach for molecular dynamics simulations. It is aimed at bridging discrete scales with either coarse grained discrete or continuum scales. The method consists of the waveform relaxation scheme aimed at capturing the high frequency response of atomistic vibrations and a coarse scale solution in space and time aimed at resolving smooth features (in both space and time domains) of the discrete medium. The method is implicit in space and time, possesses superior stability properties and consequently enables larger time steps governed by accuracy considerations of coarse scale quantities of interest. Performance studies on polymer melts have shown significant speed-up compared to the classical explicit methods, in particular on parallel machines.
