We present initial results for 2-D convective evolution of the post-bounce epoch of a model for stellar core collapse. This model incorporates a fully coupled treatment of the order (v/c) radiation-hydrodynamic equations. The model consists of a Woosley-Weaver 15 solar mass precollapse progenitor (S15S7B2) that has been evolved through collapse using a 1-D Lagrangean multigroup flux-limited diffusion (MGFLD) radiation-hydrodynamics code. The composition and thermodynamic state of the material, for both pre- and post-collapse, is described by the Lattimer Swesty EOS, which has been implemented via a thermodynamically consistent tabular interpolation scheme. A standard suite of neutrino-matter interations are included in the model. All three neutrino/anti-neutrino species are evolved. The 1-D code is used to follow the model until the post-bounce shock stalls. The 1-D results then are subsequently evolved on a 2-D polar coordinate grid using a 2-D Eulerian MGFLD radiation-hydrodynamics code. The 2-D evolution allows asymmetric instabilities to develop and describes features that cannot develop in 1-D models.
