WiseCFD V2023: A software framework with open architecture to support verification and validation and credibility assessment of CFD software

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.
