The Brownian dynamics (BD) method is used to solve two case studies for the position distribution of a particle in: (1) a flowing fluid under no external force and Brownian diffusion; and (2) a quadratic energy well with Brownian diffusion. For both cases, the explicit Euler stochastic differential equation (SDE) method is employed [1].
