CCP-WSI+ Collaborative Computational Project on Wave Structure Interaction +

拟议的新CCP-WSI+建立在波浪结构相互作用合作计算项目（CCP-WSI）产生的影响的基础上，并将其扩展到将计算流体动力学（CFD）和计算结构力学（CSM）中以前独立的社区连接在一起。新的CCP-WSI+合作建立在NWT的基础上，将加速开发适用于处理近海和海岸工程最新挑战的全耦合波浪结构相互作用（FCWSI）模型。自2015年成立以来，CCP-WSI为WSI社区提供了战略领导，并成功地在以下方面产生了影响：战略制定，知识贡献，战略软件开发和支持。现有的CCP-WSI网络已通过行业焦点小组研讨会确定了WSI代码开发的优先事项;通过国际公认的盲测系列提高了对WSI适用性和可靠性的理解;并支持协作代码开发。加速海上可再生能源部门和保护沿海社区是英国的战略优先事项，涉及复杂的WSI挑战。设计人员需要能够处理复杂环境载荷条件和复杂结构的计算工具，并对其可靠性和适当使用充满信心。计算工具对于这些优先领域的设计和评估至关重要，需要继续支持其开发、适当利用和实施，以利用HPC架构的最新进展。CFD和CSM社区都面临着类似的挑战，需要计算效率高的代码开发，适用于越来越复杂和规模的设计案例的模拟。许多不同的代码可在商业上获得，并在学术界开发，但它们在不同应用中的可靠性以及模拟质量的独立定性测量仍然存在相当大的不确定性。我们建议将在各自领域引领发展的两个联合王国专家团体聚集在一起。其动机是开发FCWSI软件，该软件将一流的CFD工具与计算固体力学的最新创新相结合。CCP-WSI+将通过一系列网络活动和行业研讨会将CFD和CSM社区聚集在一起，旨在分享跨学科的良好实践和交流进展，并为下一代FCWSI工具制定路线图。培训和研讨会将支持代码耦合方法和库的共同创建，以支持社区使用的开源环境中使用的CFD代码范围，并帮助并行实施。CCP-WSI+将对WSI代码进行软件审计，数据库和网站将通过数据库可视化和存档进行扩展和增强，以便扩大社区的贡献。代码开发将通过提供和管理代码库，用户支持和软件工程培训以及耦合和并行化的最佳实践来支持。通过将两个独立研究流体和结构新计算方法的研究人员社区聚集在一起，我们相信，我们将能够共同设计下一代FCWSI工具，在流动物理和结构响应方面都具有现实性，并且通过这种方式，将在海洋和海岸工程中开启新的复杂应用

The proposed new CCP-WSI+ builds on the impact generated by the Collaborative Computational Project in Wave Structure Interaction (CCP-WSI) and extends it to connect together previously separate communities in computational fluid dynamics (CFD) and computational structural mechanics (CSM). The new CCP-WSI+ collaboration builds on the NWT, will accelerate the development of Fully Coupled Wave Structure Interaction (FCWSI) modelling suitable for dealing with the latest challenges in offshore and coastal engineering.Since being established in 2015, CCP-WSI has provided strategic leadership for the WSI community, and has been successful in generating impact in: Strategy setting, Contributions to knowledge, and Strategic software development and support. The existing CCP-WSI network has identified priorities for WSI code development through industry focus group workshops; it has advanced understanding of the applicability and reliability of WSI through an internationally recognised Blind Test series; and supported collaborative code development.Acceleration of the offshore renewable energy sector and protection of coastal communities are strategic priorities for the UK and involve complex WSI challenges. Designers need computational tools that can deal with complex environmental load conditions and complex structures with confidence in their reliability and appropriate use. Computational tools are essential for design and assessment within these priority areas and there is a need for continued support of their development, appropriate utilisation and implementation to take advantage of recent advances in HPC architecture. Both the CFD and CSM communities have similar challenges in needing computationally efficient code development suitable for simulations of design cases of greater and greater complexity and scale. Many different codes are available commercially and are developed in academia, but there remains considerable uncertainty in the reliability of their use in different applications and of independent qualitative measures of the quality of a simulation.One of the novelties of this CCP is that in addition to considering the interface between fluids and structures from a computational perspective, we propose to bring together the two UK expert communities who are leading developments in those respective fields. The motivation is to develop FCWSI software, which couples the best in class CFD tools with the most recent innovations in computational solid mechanics. Due to the complexity of both fields, this would not be achievable without interdisciplinary collaboration and co-design of FCWSI software.The CCP-WSI+ will bring the CFD and CSM communities together through a series of networking events and industry workshops designed to share good practice and exchange advances across disciplines and to develop the roadmap for the next generation of FCWSI tools. Training and workshops will support the co-creation of code coupling methodologies and libraries to support the range of CFD codes used in an open source environment for community use and to aid parallel implementation. The CCP-WSI+ will carry out a software audit on WSI codes and the data repository and website will be extended and enhanced with database visualisation and archiving to allow for contributions from the expanded community. Code developments will be supported through provision and management of the code repository, user support and training in software engineering and best practice for coupling and parallelisation.By bringing together two communities of researchers who are independently investigating new computational methods for fluids and structures, we believe we will be able to co-design the next generation of FCWSI tools with realism both in the flow physics and the structural response, and in this way, will unlock new complex applications in ocean and coastal engineering
