Many astrophysical objects display complex multi-dimensional behavior. In order to fully understand many of these objects, it is necessary to compute flows of gas which are made up of an arbitrary mixture of nuclear species. There are at least two types of situations where following abundance changes is crucial. One is in the propagation of detonation and deflagration fronts such as those occurring in supernovae, novae, X-ray bursts, gamma-ray bursts, and shell flashes in stars. Here, the nuclear energy released by the propagation of the burning front is directly related to the composition of the material ahead of the front. A second important class of calculations involves determing the amount of mixing of nuclear species which occurs in stars. This paper describes the development of a numerical code for studying these processes.
