Efficient Numerical Simulation of Advection Diffusion Systems

Numerical simulation is used to study the dynamics of fluids under conditions that make physical experiments and theory intractable. To perform these numerical simulations, scalable, efficient numerical solvers are needed. In this talk I will describe how the Fast Diagonalization Method can be used in conjunction with domain decomposition methods and iterative methods to produce efficient solvers and preconditioners for numerical simulation of steady advection-diffusion systems.

Speaker Bio: P. Aaron Lott is a Ph.D. candidate in Applied Mathematics and Scientific Computation at the University of Maryland, College Park. He has been working with Professors Howard Elman and Anil Deane to develop efficient solvers for spectral element discretizations of the steady advection-diffusion and Navier-Stokes equations.
