Room: Executive Salon 1
Radiation transport (photonic or particulate) is an important effect in simulations of combustion, stars, and nuclear reactors and weapons. The models are very expensive to compute, since they add 3 dimensions at every grid point (2 angular and 1 energy). They raise numerical analysis issues for gridding and discretization strategies, iterative versus direct solvers, and methods for accelerating convergence. Parallel computation poses additional challenges because of directional and long-range effects. The speakers in this minisymposium will discuss the discrete ordinates methods commonly used to solve the radiation equations, parallel strategies and successes, and challenges for the future.
