We present preliminary results from recent computer simulations of the post-bounce phase of a core-collapse supernova model. This model employs V2D, our new code, which couples hydrodyanmics and neutrino radiation in two spatial dimensions, and uses multigroup flux-limited diffusion.
In two-dimensional models, our current calculations show the rapid post-bounce onset of instabilities in two regions: behind the bounce shock wave and in the proto-neutron star. We observe convection forming in both these regions.
