We study the hydrodynamic evolution of a non-spherical core-collapse supernova in three-dimensions. We begin our study from the moment of shock revival - taking into account neutrino heating and cooling, nucleosynthesis, convection, SASI-type instabilities of the supernova shock - and continue for the first 3 months after the explosion when the expanding flow becomes homologous and the ejecta enter the early supernova remnant phase. We observe the growth and interactions of the fluid flow instabilities, aided by radioactive heating at late times, resulting in an extensive mixing of the heavy elements throughout the ejecta. Analysis of our results provides information to what degree supernova remnants preserve memory about the explosion phase.
