摘要

像计算流体动力学软件OpenFOAM这样的开源环境对研究小组非常有吸引力,因为它们允许对新模型或概念进行有效的原型设计。然而,要使下游发展可持续,即在长期内可复制和可重复使用,必须考虑到大量的维护工作。为了允许增长和可扩展性,维护工作应该以高度自动化的重复性任务为基础,例如构建测试、代码部署和验证运行,以便将重点放在科学工作上。本文提出了一个与反应堆冷却剂系统安全研究相关的插件代码和设置文件集中维护的信息技术环境。它促进协作开发和审查过程。最先进的管理软件开发的工具是为了满足OpenFOAM的要求而设计的。提出了一种灵活的升级底层安装的方法,基于OpenFOAM开发线的快照而不是年度版本发布,以便在相关研究项目需要时提供新功能。在所谓的冲刺周期内,升级过程伴随着几项检查,以确保下游代码和模拟设置的兼容性。此外,还为从提供的仿真设置中构建验证数据库奠定了基础,为持续的质量保证奠定了基础。

Sustainable development of simulation setups and addons for OpenFOAM for nuclear reactor safety research
Abstract Open-source environments such as the Computational Fluid Dynamics software OpenFOAM are very appealing for research groups since they allow for an efficient prototyping of new models or concepts. However, for downstream developments to be sustainable, i.e. reproducible and reusable in the long term, a significant amount of maintenance work must be accounted for. To allow for growth and extensibility, the maintenance work should be underpinned by a high degree of automation for repetitive tasks such as build tests, code deployment and validation runs, in order to keep the focus on scientific work. Here, an information technology environment is presented that aids the centralized maintenance of addon code and setup files with relation to reactor coolant system safety research. It fosters collaborative developments and review processes. State-of-the-art tools for managing software developments are adapted to meet the requirements of OpenFOAM. A flexible approach for upgrading the underlying installation is proposed, based on snapshots of the OpenFOAM development line rather than yearly version releases, to make new functionality available when needed by associated research projects. The process of upgrading within so-called sprint cycles is accompanied by several checks to ensure compatibility of downstream code and simulation setups. Furthermore, the foundation for building a validation data base from contributed simulation setups is laid, creating a basis for continuous quality assurance.
