U.S.- France Cooperative Research: Multiresolution and Multiscale Algorithms on Unstructured Meshes for Computational Sciences

0072863 Chan美国三年奖-法国在先进计算研究方面的合作研究涉及洛杉矶的加州大学的Tony Chan、美国航天局信息科学理事会的Tim Barth、艾姆斯、索菲亚安提波利斯的法国国家计算机科学与工程研究所（INRIA）的埃尔韦Guillard和波尔多大学的Remi Abgrall。该研究合作旨在开发和分析基于多尺度和多分辨率算法的离散化方法和求解器;在先进的计算架构上有效实施新的离散化和求解器;以及计算流体动力学和结构力学的应用。该奖项代表了美国方面向NSF和法国国家计算机科学与工程研究所（INRIA）提出的联合提案。 NSF将承担美国研究人员、博士后研究人员和研究生的旅费和生活费。 INRIA将支持法国研究人员访问美国。 合作是跨学科的。 美国研究人员在椭圆和双曲问题的多重网格方法的理论和分析方面都是专家。 法国在计算流体动力学和双曲问题的多分辨率算法方面的专业知识对此进行了补充。 该项目将促进对所提出的方法和算法及其在粒子物理学，流体动力学和宇宙学问题中的应用的理解。

0072863ChanThis three-year award for U.S.-France cooperative research in advanced computational research involves Tony Chan of the University of California at Los Angeles, Tim Barth of the Information Sciences Directorate, NASA Ames, Herve Guillard of the French National Institute for Research in Computer Science and Engineering (INRIA) in Sophia Antipolis and Remi Abgrall of the University of Bordeaux. The research collaboration is aimed at the development and analysis of discretization methods and solvers based on multiscale and multiresolution algorithms; efficient implementation of the new discretization and solvers on advanced computing architectures; and applications to computational fluid dynamics and structural mechanics. This award represents the U.S. side of a joint proposal to the NSF and the French National Institute for Research in Computer Science and Engineering (INRIA). NSF will cover travel funds and living expenses of the U.S. investigators, postdoctoral researchers and graduate students. INRIA will support the French researchers' visits to the United States. The collaboration is interdisciplinary. The US investigators are expert in the theory and analysis of multigrid methods for both elliptic and hyperbolic problems. This is complemented by French expertise in computational fluid dynamics and on multiresolutional algorithms for hyperbolic problems. The project will advance understanding of the proposed methods and algorithms and their applications to problems in particle physics, fluid dynamics, and cosmology.
