At the present time even the most sophisticated, multi-dimensional
simulations of core-collapse supernovae do not (self-consistently) include
neutrino flavor transformation. This physics is missing despite the importance
of neutrinos in the core-collapse explosion paradigm. Because of this
dependence, any flavor transformation that occurs in the region between the
proto-neutron star and the shock could result in major effects upon the
dynamics of the explosion. We present the first hydrodynamic core-collapse
supernova simulation which simultaneously includes flavor transformation of the
free-streaming neutrinos in the neutrino transport. These oscillation
calculations are dynamically updated and evolve self-consistently alongside the
hydrodynamics. Using a $M=20\;M_ødot$ progenitor, we find that while
the oscillations have an effect on the neutrino emission and the heating rates,
flavor transformation alone does not lead to a successful explosion of this
progenitor in spherical symmetry.
