项目摘要

Within the past two decades, scientific computing has become an important contributor to all scientific research programmes. It is particularly important for the solution of research problems that are either insoluble by traditional theoretical and experimental approaches or are hazardous to study in the laboratory, time consuming or expensive to solve by traditional means. However, critical to many areas of computation is the ability to represent a geometry and problem domain in a discretised manner. This important and critical step is the generation of a suitable computational mesh. For simple test problems, the generation of a suitable mesh is trivial, but, for most problems of practical interest, the generation of a mesh is a significant challenge. Whilst major progress has been made, it is still the case that the major problems encountered, when applying computational methods to new and emerging areas of science and engineering, often involve the generation of a suitable mesh. It is also worth emphasising that the most common source of failures during a simulation can frequently be traced to an inadequate mesh, while the accuracy of a simulation is highly dependent upon the mesh quality.Past developments within the Group have been applied to a diverse setof problems in many fields, including aerospace, automotive, electronics, biomechanics, construction, geography, geotechnics and oil reservoir modelling. A particularly successful application area has been the aerospace industry, with its design requirement for accurate, rapid analysis of flows over aircraft configurations.A clear strategy of the Group has been to pursue the use of unstructured mesh technology driven by applications. Applications provide the challenges that highlight deficiencies in a method that then leads to basic research and theoretical understanding that will then result in an enhanced capability.The proposed work will address many of the deficiencies that are currently restricting the wider use of computational simulation. In particular, problems associated with geometries will be emphasised and new and innovative techniques will be investigated for their solution. Furthermore, new methods of generating high quality meshes that can maximise the efficiency of solution algorithms will be explored. These developments will be made available through the use of recent developments in computer technology, such as the GRID and web services.

在过去的二十年中，科学计算已成为所有科学研究项目的重要贡献者。对于解决传统理论和实验方法无法解决的研究问题尤其重要，或者通过传统方法解决在实验室中研究存在危险、耗时或昂贵的研究问题。然而，对于许多计算领域来说至关重要的是能够以离散方式表示几何和问题域。这个重要且关键的步骤是生成合适的计算网格。对于简单的测试问题，生成合适的网格是微不足道的，但是，对于大多数实际感兴趣的问题，生成网格是一个重大挑战。尽管已经取得了重大进展，但当将计算方法应用于新兴的科学和工程领域时，遇到的主要问题仍然是经常涉及合适网格的生成。还值得强调的是，模拟过程中最常见的故障源通常可以追溯到网格不充分，而模拟的准确性在很大程度上取决于网格质量。集团过去的开发成果已应用于许多领域的各种问题，包括航空航天、汽车、电子、生物力学、建筑、地理、岩土工程和油藏建模。航空航天业是一个特别成功的应用领域，其设计要求对飞机配置上的流量进行准确、快速的分析。该集团的明确战略是追求使用由应用驱动的非结构化网格技术。应用程序提出的挑战突出了方法中的缺陷，然后导致基础研究和理论理解，从而增强了能力。拟议的工作将解决目前限制计算模拟更广泛使用的许多缺陷。特别是，将强调与几何相关的问题，并将研究新的创新技术来解决这些问题。此外，还将探索生成高质量网格的新方法，从而最大限度地提高求解算法的效率。这些发展将通过使用计算机技术的最新发展来实现，例如网格和网络服务。
