An effective viscosity coefficient depending on the averaging time was introduced and displayed graphically. The results showed that the required ensemble average can also be obtained from shorter parallel runs starting from statistically independent initial states.Keywords: Boundary conditions; Computer simulation; Molecular dynamics; Relaxation processes; Stress analysis; Viscoelasticity; Stress fluctuations; Viscosity of liquidsCrossover between short-and long-time behaviour of stress fluctuations and viscoelasticity of liquids20032015-12-12
