Development and open source application progress of NNW-PHengLEI
摘要
Abstract
Computational fluid dynamics(CFD)software constitutes a vital part of industrial software,and can be categorized into types such as commercial,in-house code,open-source software,each serving distinct requirements,application scenarios,and functional characteristics.As one of the foundational computational platforms of China's National Numerical Wind-tunnel(NNW)project,PHengLEI was open-sourced nationwide in 2020,with the goal of building independent CFD infrastructure and a supporting ecosystem.This paper provides a systematic review of its latest R&D progress,technical features,and representative application cases.It first discusses the significance of open source for developing indigenous fluid dynamics industrial software and surveys the current landscape of well-known open-source CFD software both domestically and internationally.The development history and latest technical advances of PHengLEI are then outlined,with focus on its highly extensible framework design,efficient large-scale parallel computing capabilities,and recent progress in mesh generation,flow solving,and wind-energy applications for civilian needs.Furthermore,the application status since its open-source release is briefly summarized,illustrated through three representative cases that showcase its practical implementation patterns.Finally,existing technical shortcomings and directions for improvement are analyzed.In light of emerging open-source practice paradigms in the industrial software field,we advocate for collaborative innovation through open-source communities to enhance the technical system and engineering capabilities,thereby fostering the sustainable development of China's independent fluid dynamics industrial software ecosystem.关键词
