我们报告完成的第一个版本的新一代仿真代码，FLASH。FLASH代码解决了完全可压缩的反应流体动力学方程，并允许使用自适应网格细化。它还包含状态方程和热核反应网络的最新模块。FLASH程序是为了研究中子星和白色矮星表面以及白色矮星内部的核闪光问题而开发的。然而，我们期望FLASH代码将有助于解决各种各样的其他问题。这个代码的第一个版本已经进行了大量的测试用例，目前正在用于X射线爆发，瑞利-泰勒和里希特迈尔-梅什科夫不稳定性和热核火焰前沿的生产模拟。FLASH代码是可移植的，并且已经在各种各样的大规模并行机器上运行，包括一些现存的最大的机器。
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.
