The discovery of Enceladus" plume raised important questions pertaining to the interaction of Saturn's magnetosphere with this small moon. Traditional MHD as well as several other plasma dynamic simulations assume a collisionless plasma, and generally exclude the possibility for charge exchange and momentum transfer between neutrals and plasma. The interaction of Saturn's magnetosphere with Enceladus and its plume provides an exciting natural laboratory for expanding our understanding of change-neutral interactions and their impact on mass and momentum loading of the system and the associated magnetic perturbations. Here we present a simulation that treats several ion and neutral species in a multi-fluid simulation approach that incorporates both the plasma dynamics and neutral-ion interactions responsible for energy and momentum transfer between the neutral and ion fluids. These simulations are compared in detail to and benchmarked against the observations made from the recent Enceladus flyby on March 12, 2008, and can potentially lead to interpretation of features observed in the ion population by CAPS.
