Preprocessing is an important link in the finite element analysis process, and the visualization capability of preprocessing is of great significance for reducing errors and improving efficiency.This paper introduces the development of LinkFEA software. The software is based on the Qt framework and uses the VTK library to implement preprocessing data visualization, graphics interaction, and mesh generation functions. The software is written in C++, supports the import and parsing of multiple mesh formats, and has the ability to view and modify meshes in real time. In the development process of the software, we used open source software and carried out secondary development to meet the needs of preprocessing visualization in engineering applications.精品文档---下载后可任意编辑Through practical applications, we can find that LinkFEA software has good compatibility and stability, which can help users quickly master the preprocessing process and improve work efficiency. At the same time, we found some problems in the development process of the software, such as graphics drawing efficiency, mesh import and parsing, etc. These problems need to be further optimized and improved in the subsequent development process.Keywords: finite element analysis; preprocessing; visualization; open source software; LinkFEA
