Openfoam computing task management method based on web technology

Abstract

The present invention provides an OpenFOAM computing task management method based on Web technology. The method is based on Web technology, provides unified, convenient and visualized OpenFOAM cloud computing task management and post-processing visual operation interface and API communication interface, and provides CFD for multi-user usage scenarios. The calculation task creation and management mechanism, users do not need to master the remote login and operation skills of the server, and do not need to understand the OpenFOAM calculation details, which significantly reduces the operation difficulty of the OpenFOAM application in the process of building CFD-aided design; this method also uses the CFD multi-task management program. Personnel on duty avoids waste of resources caused by manual monitoring and untimely error handling; through automatic allocation of computing resources, it avoids resource competition caused by multi-user use, resulting in reduced efficiency; fully utilizes the multi-core high-performance parallel computing capabilities of computing servers to maintain The server can continuously and efficiently carry out CFD analysis of construction projects, providing a new technical means for CFD batch automatic calculation.

Description

technical field [0001] The invention belongs to the field of digital CFD software development of construction engineering, and particularly relates to an OpenFOAM computing task management method based on Web technology. Background technique [0002] In the context of the digital transformation of the construction industry, engineering requirements such as green building assessment in the civil field and wind resistance analysis of over-limit complex buildings have increasingly higher requirements for fluid mechanics analysis tools. The computational fluid dynamics (CFD) software OpenFOAM has become one of the main general-purpose computational fluid dynamics CFD software at home and abroad because of its open source, strong scalability and support for free parallel algorithms. The software is developed based on the open-source operating system Linux and C++ language. It can solve compressible, incompressible, laminar, turbulent, multiphase, and buoyant thermodynamic driven ...

Problems solved by technology

[0003] However, the application of the OpenFOAM open-source CFD algorithm to the current field of architectural engineering aided design still has the following shortcomings: 1) The software lacks a visual graphical interface, and all grid and calculation parameter configurations are completed in script files. CAD design software docking; 2) Proficiency in this software requires users to master the Linux open source operating system, C++ programming language and basic knowledge of computational fluid dynamics, which is difficult for general engineering designers; 3) All configurations of the software need to be manually configured , the various configurations are interrelated and need to be linked and modified at the same time to be executed smoothly. User manual operations cannot automatically complete error checking, which is prone to omissions
