Establishment Of FE Experimental Platform

The emphasis of this paper studies the post-processing program of visual finite element method software "VFEM 3.0" and establishes finite element software "experimental platform".This software is composed of three modules:the pre-processing, analysis and calculation and post-processing.In the pre-processing,it includes automatic generation of structural meshes,adding contraints and loads and so on;In the analysis and calculation,the wave-front is used to calculate and establish data files related;In the post-processing,strong and visual function of VC++ is utilized to display structural deformation graph,contours as well as color cloud pictures.In this last processing,deformation graphs are divided into two types-boundary deformation graph and entire deformation graph in order to show deformation condition entirely; contour graph comprises isodisplacement graph and isostress graph;color cloud picture comprises cloud picture of displacement and that of stress,whose drawing principle is isoparametric mapping method.Communicative technology between processes of VC++ is used to start new process and link three modules of finite element so that we can generate a integered software "experimental platform" of finite element .The software has friendly interface,which is convenient to operate.
