Measuring the ventilation rate is crucial to ensuring the control of thermal comfort, energy saving, and emission of pollutants in greenhouses and animal houses. This is more difficult in naturally ventilated (NV) buildings because of the dynamic and complex air flow patterns caused by wind and buoyancy effects. In this study, a user-friendly computational fluid dynamics (CFD) simulator is developed to analyse internal airflow patterns and ventilation rates of NV buildings, with the initial focus on agricultural buildings. The user-friendly CFD automation program, developed using the freely available open-source OpenFOAM and ParaView visualization toolkit, is aimed at non-CFD experts to help them obtain practical CFD solutions quickly. Users simply input building and ventilating configurations, outdoor wind conditions, topographical conditions, and information regarding plants or animals through user-friendly graphical user interfaces. General CFD processes are automated, and the quality of each process is controlled. After executing the program, a three-dimensional interactive visualization module is used for post-processing. It can ensure the flexibility and manageability of the model by automating predeveloped procedures in a user-interactive manner, thereby reducing time and effort. This paper describes the development process of automation interfaces.

非专家的计算流体动力学：为自然通风设计应用开发用户友好的 CFD 模拟器 (HNVR-SYS)

测量通风率对于确保控制温室和畜舍的热舒适性、节能和污染物排放至关重要。由于风和浮力效应导致动态和复杂的气流模式，这在自然通风 (NV) 建筑中更加困难。在这项研究中，开发了一种用户友好的计算流体动力学 (CFD) 模拟器来分析 NV 建筑物的内部气流模式和通风率，最初的重点是农业建筑。用户友好的 CFD 自动化程序使用免费提供的开源 OpenFOAM 和 ParaView 可视化工具包开发，旨在帮助非 CFD 专家快速获得实用的 CFD 解决方案。用户只需输入建筑和通风配置、室外风况、地形条件、通过用户友好的图形用户界面了解有关植物或动物的信息。一般的 CFD 流程都是自动化的，每个流程的质量都是可控的。程序执行后，采用三维交互可视化模块进行后期处理。它可以通过以用户交互方式自动化预先开发的程序来确保模型的灵活性和可管理性，从而减少时间和精力。本文介绍了自动化接口的开发过程。它可以通过以用户交互方式自动化预先开发的程序来确保模型的灵活性和可管理性，从而减少时间和精力。本文介绍了自动化接口的开发过程。它可以通过以用户交互方式自动化预先开发的程序来确保模型的灵活性和可管理性，从而减少时间和精力。本文介绍了自动化接口的开发过程。
