The method of Brownian dynamics to simultate trajectories of particles diffusing under the influence of external forces is extended to the approximation of local linear forces and to reflective boundaries possibly confining the diffusion space. A simple algorithm for the generation of random diffusive displacements is developed and its validity demonstrated by comparison with analytical and numerical descriptions of sample one-dimensional diffusion distributions.
