IGERT: Modeling Complex Systems - The Scientific Basis of Coupling Multi-Physics Models at Different Scales

对湍流运输、复杂结构力学和全球气候变化等系统的精确计算模型的需求远远超过了计算能力的增长，需要开发新的方法。这个综合研究生教育和研究培训（IGERT）奖将通过研究生研究和培训来解决这一挑战，在统一的设置中，跨尺度和学科的基于科学的模型耦合。具体来说，重点将放在用于描述在使用基本科学原理的模型中不能完全计算的现象的工具上。大量文献描述了应用于特定物理过程的参数化描述。然而，关于基于科学的参数化的通用交叉应用指导原则的知识却很少。这项工作的目标是发展基于科学的模型耦合，作为指导科学和工程中计算建模实践的路线图。该教育计划将培养一批领导这些技术在工业、学术界和国家实验室应用的博士研究生。四项教育和培训目标将涉及：(1)使学生能够在多学科环境中工作；(2)培养学生成为科学和工程领域的领导者；(3)建立和维护学生的职业关系网；(4)以女性为目标，扩大美国博士学生群体？第一代大学生比例较高的美国学院和大学。每个社会成员都受到基于关键过程（如能源生产、环境保护和基础设施完整性）的计算模拟的决策或预测的影响。通过提议的IGERT进行的研究将通过为计算建模提供新的范例来解决这些重要问题。IGERT是一项nsf范围内的计划，旨在满足教育美国博士科学家和工程师的挑战，他们具有跨学科背景，所选学科的深厚知识，以及未来职业需求所需的技术，专业和个人技能。该计划旨在通过建立创新的研究生教育和培训模式，在一个超越传统学科界限的合作研究的肥沃环境中，促进研究生教育的文化变革。

The need for accurate computational models for systems such as turbulent transport, mechanics of complex structures, and global climate change have far outpaced the growth of computing power, requiring the development of new approaches. This Integrative Graduate Education and Research Traineeship (IGERT) award will address this challenge through graduate research and training in a unified setting of science-based coupling of models across scales and disciplines. Specifically, the focus will be on tools used to describe phenomena that are not fully calculable in models using fundamental scientific principles. A large body of literature exists describing parameterized descriptions applied to specific physical processes. However, little knowledge is available on general cross-application guiding principles for science-based parameterization. The goal of this work is to develop science-based model coupling as a roadmap to guide the practice of computational modeling in science and engineering. The education plan will train a cadre of Ph.D. students who will lead the application of these techniques in industry, academia and national laboratories. Four education and training goals will be addressed: (1) Enable students to work in a multi-disciplinary setting; (2) Develop students to be leaders in science and engineering; (3) Establish and maintain a career-long network for students; (4) Expand the U.S. Ph.D. student base by targeting students at women?s colleges and universities with a large percentage of first-generation college students. Every member of society is affected by decisions or predictions based on computational simulations of critical processes, such as energy production, environmental protection, and infrastructural integrity. The research conducted through the proposed IGERT will address these important problems by providing new paradigms for computational modeling. IGERT is an NSF-wide program intended to meet the challenges of educating U.S. Ph.D. scientists and engineers with the interdisciplinary background, deep knowledge in a chosen discipline, and the technical, professional, and personal skills needed for the career demands of the future. The program is intended to catalyze a cultural change in graduate education by establishing innovative new models for graduate education and training in a fertile environment for collaborative research that transcends traditional disciplinary boundaries.
