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

[0072863]这项为期三年的高级计算研究美法合作研究奖包括洛杉矶加利福尼亚大学的Tony Chan、信息科学理事会的Tim Barth、NASA Ames、位于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Herve Guillard和波尔多大学的Remi Abgrall。研究合作的目的是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；新型离散化求解器在先进计算体系结构上的高效实现以及在计算流体力学和结构力学中的应用。该奖项代表了美国方面向美国国家科学基金会和法国国家计算机科学与工程研究所（INRIA）提出的联合提案。美国国家科学基金会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。这种合作是跨学科的。美国的研究人员在椭圆型和双曲型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也对这一点进行了补充。该项目将促进对所提出的方法和算法及其在粒子物理、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.
