Description/AbstractIn one dimension, we present results from comparisons of stationary state multi-group flux-limited diffusion and Boltzmann neutrino transport, focusing on quantities central to the postbounce shock reheating. In two dimensions, we present results from simulations that couple one-dimensional multigroup flux-limited diffusion to two- dimensional (PPM) hydrodynamics.
