Particle Simulation Of Three-dimensional Modeling Platform For Research And Design

With the development of computer technology, particle simulation method is widely known as a hot subject. Computer powerful computing capability in complex physical particle simulation provides a solution to the problem. Particle Simulation need to simulate the interaction between charged particles and electromagnetic fields, PIC (particle-in-cell) method to achieve its development from linear to nonlinear, computer-aided design (CAD) technology is an important means of PIC assisted method development.Computer powerful computing capability, large capacity storage and fast data processing and graphics capabilities enable CAD technology has a simple design and easy to modify the flow characteristics, can be a good help technical staff to reduce labor intensity, to focus better on the overall design of the model, while reducing design cycle and improve design quality. There are many domestic and foreign particles or electromagnetic simulation calculation software category, its advantages and disadvantages and this paper, we introduce limitations were analyzed, and the University of Electronic Science and Technology has CHIPIC3D software is completely independent intellectual property rights were introduced.Research and achieve the objectives of this paper:to design a three-dimensional modeling platform CHIPIC3D calculation program. First, the need for a variety of physical problems and modeling processes analysis, similar physical subregional discussion and analysis of functional requirements while providing corresponding solutions.Through a variety of development platforms and development tools for comparison and discussion, analyzing the advantages and disadvantages of various graphical development platform, and finally due to the advantages of the powerful Qt cross-platform migration capabilities, rich graphics and controls widget libraries, decided to herein chosen Qt as a development platform. In the Select a 3D graphics toolkit on for OpenGL open graphics library a brief introduction, based on OpenGL powerful 3D graphics processing power and excellent cross-platform capabilities decided to use OpenGL as the graphics-based processing library particle simulation of three-dimensional model of the platform.In the framework of the three-dimensional model design platform and choose the MVC design thinking as the main framework, MVC application framework design ideas into the control layer, model layer, view layer three levels, so that the benefits of layered art can put most of the effort to develop the model layer independent of each module. While the second chapter of various physical models mentioned classification, model class inherits from the general category of Mesh class CVolume class; control provides basic functions of the various interfaces and software; providing interactive interface class view interface. While a variety of needs and problems in the course of the software of feedback to improve functionality.Finally, a variety of high-power microwave devices for three-dimensional modeling of three-dimensional model on a platform, mastered the three-dimensional model of the design process platform, the engineering staff have great help in work efficiency and overall modeling.
