We present a multidimensional study of prompt convection in core collapse supernovae. The initial conditions for prompt convection, obtained from realistic one-dimensional simulations implementing multigroup flux-limited diffusion, are discussed, and the development of prompt convection and its ramifications for the supernova outcome are investigated in one and two dimensions. In one dimension, mixing length theory is used. In two dimensions, the hydrodynamics is evolved using an extended version of the piecewise parabolic method code VH-1, with running boundary conditions specified using our one-dimensional simulations. A comparison is made between the one- and two-dimensional outcomes. In particular, for a given set of initial conditions, we focus on the differences, if any, in prompt convection. We discuss the ramifications of our results for supernova modeling.
