Abstract :
Astrophysical flows typically span a broad range of length and time scales. Specialized numerical algorithms can exploit the relationships between these scales and significantly improve the efficiency of numerical simulations without loss of accuracy. The authors describe the process by which an understanding of the important processes in Type Ia supernovae is guiding the development of new algorithms to model these phenomena.
