Discrete Diffusion Monte Carlo for Electron Thermal Transport
POSTER
Abstract
The iSNB (implicit Schurtz Nicolai Busquet\footnote{Schurtz et. al. Phys. Plasmas \textbf{7}, 4238 (2000)} electron thermal transport method of Cao et. al.\footnote{Cao et. al. J. Comput. Phys$.$ (Submitted 2014)} is adapted to a Discrete Diffusion Monte Carlo (DDMC) solution method for eventual inclusion in a hybrid IMC-DDMC (Implicit Monte Carlo) method. 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 iSNB-DDMC method will be presented.
