基于web技术的有限元模型和成果可视化方法研究OACSTPCD

In the design and operation stages of water conservancy and hydropower projects,finite element analysis(FEA)is often used to analyze the structural forces and deformations.In the past,the finite element analysis results are mostly presented to the design or operation management units by universities or research institutes in the form of research reports with fixed charts and graphs,which makes it impossible for the design or operation management units to understand the new calculation results in real time in case of changes in the boundary conditions or material parameters.With the development of Web technology,it is possible to present the finite element model and analysis results to designers and operation personnel in a visual and interactive way in real time.By using the Three.js framework based on the WebGL technology closure,the visual presentation of the three-dimensional finite element mesh model of arch dam and the analysis results in the user's browser is achieved,which allows the user to interactively browse the finite element model and the analysis results of the dynamic browsing and viewing,so as to facilitate the user to understand the results of the calculations in a comprehensive manner.This method provides online query technology of calculation and analysis results for the construction of digital twin water conservancy project,which has wider application.
