天体物理热核闪光中心正在构建新一代代码，旨在研究演化致密恒星表面或内部失控的热核燃烧。该中心已经完成了Flash的第一个版本，Flash-1，它解决了各种天体物理问题。Flash-1代表着朝着解决一般天体物理流体动力学问题的完全灵活的代码方向迈进了一大步。Flash-1是模块化和自适应的，可以在并行计算环境中运行。它的设计目的是让用户只需最少的努力就可以配置初始和边界条件、更改算法和添加新的物理效果。它使用参数网格库来管理块结构的自适应栅格，只将分辨率元素放置在最需要的位置。它还使用消息传递接口(MPI)库在各种不同的消息传递并行计算机上实现可移植性和可伸缩性。
The Center for Astrophysical Thermonuclear Flashes is constructing a new generation of codes designed to study runaway thermonuclear burning on the surface or in the interior of evolved compact stars. The center has completed the first version of Flash, Flash-1, which addresses various astrophysics problems. Flash-1 represents a major advance toward a fully flexible code for solving general astrophysical fluid dynamics problems. Flash-1 is modular and adaptive and operates in parallel computing environments. It was designed to let users configure initial and boundary conditions, change algorithms, and add new physical effects with minimal effort. It uses the Paramesh library to manage a block-structured adaptive grid, placing resolution elements only where needed most. It also uses the message passing interface (MPI) library to achieve portability and scalability on a variety of different message passing parallel computers.
