WebbThe Metropolis algorithm provides a simple method for simulating the evolution of physical system in a heat bath to thermal equilibrium [Metropolis et al]. It is based on Monte Carlo Simulation technique, which aims to approximate the expected value of some function g(χ) of a random vector χ with a given density function fd(χ). For WebbThis method is applied to perform simulations of touching spheres arranged in a simple cubic array. Full- and reduced-stencil lattice models, i.e., theD3Q27andD3Q19, respectively, are compared and the drag force and friction factor results are presented for Reynolds numbers in the range of 0.001 to 2,477.
