Abstract:

We report on the completion of the first version of a new-generation
simulation code, FLASH.  The FLASH code solves the fully-compressible,
reactive hydrodynamic equations, and allows for the use of adaptive
mesh refinement. It also contains state-of-the-art modules for the
equations of state and thermonuclear reaction networks.  The FLASH
code was developed to study the problems of nuclear flashes on the
surfaces of neutron stars and white dwarfs, as well as in the interior
of white dwarfs. We expect, however, that the FLASH code will be
useful for solving a wide variety of other problems.  This first
version of the code has been subjected to a large variety of test
cases, and is currently being used for production simulations of X-ray
bursts, Rayleigh-Taylor and Richtmyer-Meshkov instabilities, and
thermonuclear flame fronts.  The FLASH code is portable, and already
runs on a wide variety of massively parallel machines, including some
of the largest machines now extant.
