Multi-dimensional transient partial differential systems are computationally demanding and may, for example, involve accident simulation, weather forecasting, chemical and material fabrication, turbulence, and combustion. Balancing computational loading on a parallel computer must be dynamic, since adaptivity by either h- or p-refinement will upset an initial balance. Efforts to date have concentrated on h-refinement rather than the potentially more efficient p-refinement. This research seeks to develop the technologies necessary to support effective and reliable adaptive computation for transient partial differential systems on heterogeneous parallel computing environments. These technologies will be incorporated into an extensible software framework and evaluated using applications involving fluid flow, material processing, chemical reaction, and crystal growth.

多维瞬态部分差分系统在计算范围内是要求的，例如，可能涉及事故模拟，天气预报，化学和材料制造，湍流和燃烧。平衡计算机上的计算负载必须是动态的，因为H-或P-REFINECT的适应性会破坏初始平衡。 迄今为止的努力集中在H-再填充上，而不是潜在的更有效的p填充。 这项研究旨在开发必要的技术，以支持异质平行计算环境上的瞬态部分差分系统有效和可靠的自适应计算。这些技术将纳入可扩展的软件框架中，并使用涉及流体流，材料加工，化学反应和晶体生长的应用进行评估。
