MS 81/91:   Recent Advances in Parallel Implicit Solution of Fluid Plasma Systems

2:00 PM - 4:00 PM,     4:30 PM - 6:30 PM
Room: Symphony III, Miami Hilton Downtown

Plasmas with strong electromagnetic effects are common in the natural physical world and highly important for many advanced technological applications. Plasma fluid models are typically governed by strongly coupled partial differential equations that span a very large range of time and length scales. The interacting, nonlinear multiple time-scale physical mechanisms can produce very complex dynamical behavior, making the stable, accurate, and efficient computational solution, over relevant dynamical time scales of interest, extremely challenging. This session will present state-of-the-art computational formulations and solution methods for the scalable implicit solution of fluid plasma modeling equations.
