We present two- and three-dimensional simulations of the onset and development of convection behind the stalled shock in a core collapse supernova. We begin with postbounce slices from realistic one-dimensional simulations that implement multigroup flux-limited diffusion. The multidimensional simulations include simple neutrino transport and neutrino heating and cooling of the postshock matter. They are the first in a series of simulations that will implement more sophisticated neutrino transport schemes. The hydrodynamics is evolved using an extended version of the piecewise parabolic method code VH-1, and the running boundary conditions for the two- and three-dimensional simulations are specified using our one-dimensional results. In particular, realistic time-dependent neutrino luminosity boundary conditions are used. We investigate any dimensional dependence exhibited by postshock convection. We also investigate its effect on the shock dynamics and supernova outcome.
