摘要:We introduce the ELEPHANT code and present results from a preliminary 3D simulation of a corecollapse
supernova which includes multi-group neutrino transport. Computational techniques
used for neutrino transport in two dimensions are prohibitively expensive in 3D, and three dimensional
effects such as convection and asymmetric accretion may play an important role in a
supernova explosion. The multi-group treatment based on the isotropic diffusion source approximation
allows for detailed input of microscopic physics in large-scale hydrodynamic simulations.
