A consolidated fluiddynamics algorithm for the analysis of beam dynamics under the influence of the electromagnetic field is presented. Aiming at simulating stochastic cooling of particle beams in 2D space, two numerical algorithms solving the 2D FokkerPlanck Equation are described. As an alternative approach, a numerical method based on the macroparticle tracking turn in turn in the ring (i.e. in the time domain) is introduced. Some results of the simulation of the stochastic cooling in the Collector Ring by both methods are discussed.
