摘　　要：验证与确认(V&V)是确保CFD软件及其模拟结果可信度最重要和最基础的活动。通过建立流程化、自动化的软件平台支持CFD软件验证、确认和可信度评价工作开展,有助于减少人为操作错误、大幅提高验证与确认的工作效率。从2004年第1个版本的WiseCFD平台发布以来,针对如何建立开放的CFD软件可信度评估框架,开展过很多尝试。从系统工作流程、软件架构、核心功能模块组成等方面着重介绍一种基于Web和开放架构思路实现的新一代CFD软件验证与确认应用支持平台:WiseCFD V2023,并对平台关键技术及实现进行论述。以CFD软件可信度评价指标体系为理论指导,辅以标准化的验证和确认数据库建设,并采用CFD数据及软件接口标准化技术,打通底层工具链和数据链,平台突破了针对不同类型CFD软件的开放集成、针对不同类型计算作业的开放工作流定义、基于评价指标的不同类型验证、确认和可信度评价任务的开放定义、开放的底层支持验证和确认数据库以及自动化验证和确认等关键技术,构建了一套自动化的、面向专业CFD软件验证、确认和可信度综合评价的基础软件框架。具体实现采用三层B/S软件架构,并基于微服务、容器化以及容器编排等云原生技术进行构建,便于平台的创建和部署。针对典型工程CFD软件开展的验证、确认和可信度评价场景应用示范,证实所构建验证与确认应用支持平台的可行性和有效性。Verification and Validation(V&V)are the most important and fundamental measures to ensure credibility of CFD software.Since the first version of the so-called WiseCFD platform published on 2004 to support CFD V&V,many efforts have been made to establish an open framework to support credibility assessment of CFD software as well.In this paper,the WiseCFD V2023 platform is presented,which is towards establishing an open framework to support V&V and credibility assessment of CFD software on Web.The new platform is developed based on the theory of credibility evaluation index system,and with technologies for standard V&V database,as well as technologies for standard interface of CFD data and software to breakthrough the key technologies such as open integration for different CFD software,open work flow definitions for different computation jobs,open definitions of V&V and credibility assessment tasks based on different choices of evaluation indexes,open V&V database behind the platform,and automatic verification and validation.The software platform is implemented with 3-level B/S software architecture,and is established through cloud native technologies such as microservices,containerization,and container orchestration for easy creation and deployment.The feasibility and efficiency of the presented platform is demonstrated through V&V and credibility assessment of typical CFD software for engineering applications.
