Numerical modelling of the one-dimensional diffusion by random walkers
AbstractIn this paper we describe a numerical method of cellular automaton type to study the diffusion processes. The macroscopic diffusive…
Evaluation of overshooting errors in particle methods for diffusion by biased global random walk
AbstractThe adjustment of grid steps which guarantees that particles methods yield no numerical diffusion inevitably induces overshooting errors in the…
