Platform: Underpinning Technologies for Finite Element Simulation

我们的团队专注于开发有限元方法来计算模拟流体流动，特别是低马赫数，瞬态，复杂几何形状和存在强多物理场耦合的分离流体流动。这些模型可以用来预测和回答各种科学问题，从动脉旁路移植的血液流动到一级方程式赛车部件的流动，再到解释海洋是如何循环的，或者预测地球气候对大气中二氧化碳增加的反应。这些流动的统一之处在于它们具有共同的特征，比如出现在不同大小和时间范围内的漩涡；这些特征对正在研究的现象有重要影响。这些问题的范围意味着，要解决诸如人体众多动脉中的血液流动、一辆完整的一级方程式赛车或大量潮汐涡轮机之间的相互作用等重大挑战，有必要将最先进的建模技术与在大规模并行超级计算机上运行模型的能力结合起来。认识到计算机硬件的最新变化，该平台将使小组能够促进下一代开发人员提供利用尖端计算机科学的通用软件，以便以流体建模专家和计算机科学家都能访问的方式有效地使用使用新兴硬件的并行计算机。因此，这个平台将计算机科学家和计算工程师团队聚集在一个基本的多学科项目中，其双重目标是提供灵活的、国际上受尊敬的和广泛采用的软件库，并在这个新兴领域培养年轻的研究人员。

Our team specialises in the development of finite element methods to computationally simulate fluid flow, particularly low Mach number, transient, separated fluid flows in complex geometries and in the presence of strong multiphysics coupling. These models can be used to make predictions and answer scientific questions in problems ranging from blood flow through an arterial bypass graft to the flow over components of a Formula 1 racing car to explaining how the ocean circulates or predicting the response of the Earth's climate to increased CO2 in the atmosphere. What unifies these flows is that they have common features, such as vortices, that occur across a huge range of sizes and times; these features have a critical effect on the phenomena being studied.The range of these problem means that to address grand challenges such as the flow of blood in the numerous arteries of the human body, over a full Formula 1 car or the interaction of a massive array of tidal turbines, it is necessary to combine state-of-the-art modelling techniques with the capability to run models on massively parallel supercomputers.In recognition of the recent changes in computer hardware, this platform will enable the group to promote the next generation of developers to provide general purpose software that takes advantage of cutting edge computer science to enable effective use of parallel computers using emerging hardware in a way that is accessible to fluid modelling experts as well as computer scientists. Hence this platform brings together a team of computer scientists and computational engineers in a fundamentally multidisciplinary project, with the dual aim of providing flexible, internationally respected and widely adopted software libraries, and of training young researchers in this emerging area.
