Monte Carlo Transport for Electron Thermal Transport

The iSNB (implicit Schurtz Nicolai Busquet\footnote{Schurtz et. al. Phys. Plasmas \textbf{7}, 4238 (2000)} multigroup electron thermal transport method of Cao et. al.\footnote{Cao et. al. BAPS DDP14 UP8.84 (2014)} is adapted into a Monte Carlo transport method in order to better model the effects of non-local behavior. The end goal is a hybrid transport-diffusion method that combines Monte Carlo Transport with a discrete diffusion Monte Carlo (DDMC).\footnote{Chenhall et. al. BAPS DDP14 UP8.81 (2014)} The hybrid method will combine the efficiency of a diffusion method in short mean free path regions with the accuracy of a transport method in long mean free path regions. The Monte Carlo nature of the approach allows the algorithm to be massively parallelized. Work to date on the method will be presented.
