Three-dimensional finite element model based on OpenGL and response cloud picture display method

Abstract

The invention provides a three-dimensional finite element model based on OpenGL and a response cloud picture display method. Aiming at the blank of post-processing visualization of finite element software at present, a post-processing visualization related program seriously depends on a software platform or a system platform, secondary development cannot be carried out on a post-processing displayprogram, and rapid display of a finite element model and a related result file of a large model cannot be realized. Based on the OpenGL library of the QT platform under Windows, the reading efficiency of the large model file is considered, and a relevant display algorithm of the large model file is compiled. According to the method, the three-dimensional finite element model file can be accurately read, and information such as units, coordinates and nodes can be stored. Visualization of the model and the response cloud picture is realized through an OpenGL related drawing function. The invention provides a method capable of carrying out finite element post-processing secondary development and rapid reading and displaying of a large model.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to an OpenGL-based three-dimensional finite element model and a response cloud image display method. Background technique [0002] With the continuous development of aerospace technology, the performance of various aircraft has made breakthroughs in different fields. The game between major powers is now not just a game between hard power. Strength checking is crucial to the design of composite structures and even the design of the entire aircraft. Appropriate, convenient and accurate finite element processing software can greatly shorten the design process, improve design accuracy and reduce design costs. In order to meet its speed requirements during service and to cooperate with its various military strategic advantages and skills, its external structure must meet higher mechanical properties than ordinary civilian aircraft. It will face many harsh and complex working condition...
