0339107FrancaThis award supports Leopoldo Franca and students from the University of Colorado-Denver in a collaboration with Lutz Tobiska of the Institute of Analysis and Numerics at the Technical University of Magdeburg, Germany. The collaboration will focus on the development of novel finite-element methods for simulating multi-scale phenomena. Particular attention will be paid to problems that involve features that are finer than the computation mesh. Multiscale phenomena are present in many applications, and the current project focuses on turbulent flows, where small features influence the large features of the flow. The outcome of the research will lead to improved simulations of large-scale problems involving various scales. The methods of analysis to be developed will contribute to the understanding and the foundations of future computational methods. Furthermore, the methods are constructed so that they can take full advantage of parallel machines, making them attractive for large-scale computations.

0339107Franca该奖项支持 Leopoldo Franca 和科罗拉多大学丹佛分校的学生与德国马格德堡技术大学分析与数值研究所的 Lutz Tobiska 合作。 此次合作将重点开发用于模拟多尺度现象的新型有限元方法。 将特别关注涉及比计算网格更精细的特征的问题。 多尺度现象存在于许多应用中，当前项目重点关注湍流，其中小特征影响流动的大特征。 研究成果将改进涉及不同尺度的大规模问题的模拟。 待开发的分析方法将有助于理解未来的计算方法并为其奠定基础。 此外，这些方法的构造使得它们可以充分利用并行机，这使得它们对于大规模计算具有吸引力。
