The simulations of nuclear production in stars and stellar explosions has made significant progress over the past few years. I will report on new developments in reveal areas. The NuGrid collaboration has integrated simulation techniques for a wide range of nuclear production sites into a uniform simulation framework. We are just finishing the first internally consistent yield data set for both low- and massive stars for solar and very-low metal content, including predictions of all species from both quiescent stellar evolution as well as supernova explosions. We have also applied the NuGrid tools to generate a Nova simulation framework, and simplified simulation tools for nuclear reaction rate impact tests are available for the interested nuclear astrophysics experimental community. The NuGrid collaboration has also enabled the investigation of nuclear reaction rate impact studies for many other astrophysics questions, for example the impact of the C12+C12 reaction on SN type Ia progenitor evolution. Finally, I will demonstrate how our improving, quantitative understanding of stellar hydrodynamics in nuclear production environments in the late phases of stellar evolution play an essential role for realistic nuclear astrophysics scenarios.
