Thermally induced magnetization reversal of small particles is studied using Langevin dynamics. The deterministic Gilbert equation of motion transforms to a stochastic partial differential equation adding a random thermal field to the effective field. The space discretization leads to a system of stochastic differential equations with multiplicative noise which is interpreted in the sense of Stratonovich and solved using the method of Heun. The ellipsoids and wires reverse by rotation if the length of the particle is
