Modeling method of three-dimensional geometric finite element

Finite element method disperses continuous substance into a batch of elements, and this can transform the problem of infinity freedom degree into the problem of finite freedom degree, and then solves it by computers. It is a powerful numerical analysis method in solving engineering problems. Before analysis using finite element method, the model to be calculated must be meshed. So, the research and implementation of algorithms for finite element mesh generation is quite important. To the problem of two-dimensional models, the existing methods of finite element mesh generation have achieved much success and on the whole fulfil the requirement of actual engineering. However, to the problem of three-dimensional models, mesh generation methods only have received a little bit of effect, so they must be researched and developed farther. Finite element analysis consists of computer design model that is stressed and analyzed for specific results. This paper proposes computer graphic exhibition design using finite element analysis. It constructs finite element model, then it uses ANSYS software to simulate the process of graphic exhibition, simulate result shows that the proposed finite element model is effective, sets up the regular finite elements in the premise of visual effects and precision, improves the real time application and practicability of the model.
