Improvements in discrete-ordinates acceleration

Conference ·
OSTI ID:5994094
Many discrete-ordinates transport codes depend upon variations of the synthesis method to achieve convergence within acceptable cost limits. An approximate process is used between iterations of the high-accuracy process in order to estimate the results of further high-accuracy iterations. Partial-current rebalance (PCR), diffusion synthetic acceleration, and consistent diffusion acceleration (CDA) are examples of this process; these approximate processes are briefly discussed and compared.
