Abstract
Linking theoretical models and observations of core collapse supernovae ultimately requires detailed three dimensional simulations of these events. This particularly holds for studies of clumping and mixing in supernova envelopes. To this end we have implemented an overlapping grid technique called the "Yin-Yang" grid. Different from a spherical polar grid the Yin-Yang grid does not suffer from axis artifacts, and a strongly inhomogeneous angular grid resolution due to the convergence of angular coordinate lines. Thus, at a given angular resolution, the Yin-Yang grid allows for considerably larger time steps than a spherical polar grid. Our aim is to simulate the late-time (seconds to hours after core bounce) evolution of supernova shockwave propagation through the stellar envelope in three spatial dimensions.
