We use asymptotic analysis to construct a domain decomposition method for a time-dependent singularly perturbed system with turning points. Together with the other numerical techniques, we develop an algorithm, which can provide accurate and efficient numerical solutions for the system.

Implicit Monte Carlo (IMC) is often employed to numerically simulate radiative transfer. In problems with regions that are characterized by a small mean free path, IMC can take a prohibitive amount of time, because many particle steps must be simulated to advance the particle through the time step.
