Fluid simulations with atomistic resolution: a hybrid multiscale method with field-wise coupling
Abstract We present a new hybrid method for simulating dense fluid systems that exhibit multiscale behaviour, in particular, systems in which a Navier–Stokes model may not be valid in parts of the computational domain. We apply molecular dynamics as ...
