Development and application of a credibility assessment platform for CFD software
摘要
Abstract
The approximations and assumptions made in computational fluid dynamics(CFD)modeling and simulations undermine the credibility of CFD results and prevent CFD software from playing a more significant role.Therefore,it is of great significance to assess the credibility of CFD software for its development and application.However,traditional credibility assessment by managing thousands of CFD simulations and processing gigantic amount of data correctly is tedious and time-consuming.To improve the efficiency of credibility assessment of CFD software,this paper develops a credibility assessment platform based on the B/S architecture and Spring Boot framework.It incorporates seven modules,including the CFD software management module,the assessment index system management module,the simulation process control module,the data post-processing module,the credibility analysis module,the report generation module,and others.These modules enable systematic and scientific quantitative assessments of CFD software according to the assessment index system.By integrating algorithm tools,standard model data,and computing resources required for CFD software credibility assessment,the platform automates standard model data downloading,sample generation,CFD job calculation and monitoring,data processing,simulation results analyzsis,and report generation,which remarkably reduces the cost and risk in the data production and processing process.A preliminary application of this platform to the evaluation of NNW-FlowStar,an independently developed software by the National Numerical Wind Tunnel Project,demonstrates that the platform is efficient,convenient,and practical in engineering applications.关键词
