The basic philosophy of large eddy simulation (LES) is to explicitly compute only those large-scale motions that are directly affected by the boundary conditions and to model the small scales. LES has always been described as attractive for engineering computations because it is significantly less computer-intensive than direct numerical simulation (DNS), yet promises to be more accurate and robust than single point closures.
