Discrete Diffusion Monte Carlo (DDMC) is a hybrid transport-diffusion method for Monte Carlo simulations in diffusive media. In DDMC, particles take discrete steps between spatial cells according to a discretized diffusion equation. Thus, DDMC produces accurate solutions while increasing the efficiency of the Monte Carlo calculation. In this paper, we(More)
Discrete Diffusion Monte Carlo (DDMC) is a technique for increasing the efficiency of Monte Carlo simulations in diffusive media. We present a new DDMC method for linear, steady-state, radiation transport on Adaptive Mesh Refinement (AMR) meshes in two-dimensional Cartesian geometry. We specifically examine the cases of (i) a regular mesh structure without(More)
