OpenFOAM computing task management method based on Web technology

Abstract

The invention provides an OpenFOAM computing task management method based on a Web technology. The method comprises the steps of providing a unified, convenient and visual OpenFOAM cloud computing task management and post-processing visual operation interface and an API communication interface based on a Web technology; and providing a CFD calculation task creation and management mechanism for a multi-user use scene. A user does not need to master remote login and operation skills of the server and does not need to know OpenFOAM calculation details, so that the operation difficulty of an OpenFOAM application in a building CFD aided design process is remarkably reduced. According to the method, unattended operation is achieved through a CFD multi-task management program, and resource waste caused by manual monitoring and untimely error processing is avoided; by automatically allocating the computing resources, efficiency reduction caused by resource competition during multi-user use is avoided; according to the invention, the multi-core high-performance parallel computing capability of the computing server is fully exerted, the server can continuously and efficiently carry out CFD analysis work of constructional engineering, and a new technical means is provided for CFD batch automatic computing.

Description

technical field [0001] The invention belongs to the field of construction engineering digital CFD software development, and in particular relates to an OpenFOAM calculation 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 evaluation in the civil engineering field and wind resistance analysis of over-limit complex buildings place higher and higher requirements on fluid dynamics analysis tools. 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 the multi-flow field analysis problems encountered in engineering, such as compressible, i...

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
