The distribution and abundance of elements synthesized during the explosionof a core collapse supernova are critical parameters in understanding thechemical evolution of galaxies and the stellar populations within thegalaxy. The presence of explosion asymmetries in supernovae alters boththe extent of the hydrodynamically mixed regions, as well as the conditionsfor burning within the supernova shock. This serves to change both thedistribution and abundance of the ejectedelements. Additionally, asymmetries in the remaining proto-neutron staraffect the r-process synthesis of very heavy elements. In this talk, Iwill discuss trends in burning processes for a range of physical conditionswhich exist in core-collapse supernova simulations. Intuition gained from1D explosion simulations will be compared against preliminary results froma 3D explosion simulation.
