A Preliminary Study On Visual Post-Process Of The Cluster FEM Supporting Remote Cooperative Design

The development of virtual enterprise is very hot in mechanical design and the integrate of CAD,CAE,CAM is current now. The key of remote Cooperative Design, remote Cooperative Analysis, remote cooperative manufacture, which based of WEB technic, is the share of information. So, the development focus is aimed at how to realize the effective information transform in time and the remote real-time operate between remote design, analysis and manufacture.CAE whose kernel is the FEM numerical analysis now acts very important role in mechanical design gradually and is the key tache of the design and manufacture in the modern enterprise. The new development of FEM numerical analysis is to parallel analysis 3-D super large structure by the Cluster composed of PC. Using the Cluster, not only could the parallel analysis be done, but also the visualization of the great of date from FEM analysis can be done by parallel technic. For the share of the result of visualization with the remote cooperative design, we can real the net post-process of the visualization result picture of remote FEM analysis by client and server.The thesis preliminarily develop the parallel calculate environment of the cluster and the correlated technic of visualization of FEM analysis result date. The thesis developed and programmed the compress of the visual FEM analysis result date.The thesis introduce the analysis process and character of 3-D finite element method firstly, then discus the parallel arithmetic of FEM and the construct of the parallel FEM analysis environment by PC. The technique and method of the visualization of result date of FEM analysis is discussed, such as free section, isosurface, isoline, color nephogram. Using the VC++ and OPENGL, the 3-D model reestablish of the FEM visual picture and the protract of the third dimension graph is discussed. At last the compress of FEM visual result using JPEG, then the high efficiency transmit of the compress result in the net in time, which provides the analysis result for the cooperative design, is discussed.In the end, we point out the next development direction in the future.
