In this paper we discuss a method for incorporating neutral fluid components into an existing 3D multi-fluid modeling infrastructure to investigate the interaction between neutral sources and the magnetospheric plasma in Saturn`s magnetosphere. This research was motivated by the discovery of a plume of water ice particles jetting outward from the southern polar region of Saturn`s moon Enceladus. Preliminary modeling studies in conjunction with Cassini spacecraft observations have demonstrated the presence of an extended source of ions likely due to charge exchange and ion production in the expanding neutral plume. While the importance of understanding the chemical interactions of Saturn`s magnetospheric plasma with the neutral plume and the associated mass and momentum loading from newly created heavy ions is generally recognized, a self- consistent model examining the neutral and ion dynamics and their interaction has yet to be fully established. In this neutral-coupled multi-fluid model, the ion and neutral fluids will interact through charge exchange and elastic collisions, and sources of plasma from photoionization and electron impact ionization will be included. The production and loss of ions and neutrals will be monitored through source and loss terms in each fluid species in each grid cell. Given significant progress, the model will be benchmarked using existing Cassini magnetometer and plasma data.
