Abstract

The invention provides with a remote finite element analysis method serving for an industry alliance. The remote finite element analysis method comprises the steps of (1) finite element template extraction, namely classifying and analyzing parts needing finite element analysis in the products of member enterprises in the industry alliance, and extracting finite element templates, including boundary condition types and analysis process parameters, (2) geometric model construction, namely performing geometric modeling on the structures of the needing finite element analysis in the products of the member enterprises in the industry alliance by use of a CAD (Computer-Aided Design) system mainly in a parametric modeling manner and a user-defined modeling manners, (3) boundary condition calibration, namely performing necessary calibration on pels, to which the boundary conditions are applied, in geometric models, thereby taking the geometric models as parameter input interfaces of finite element analysis, (4) finite element model conversion, namely converting the geometric models into finite element models by use of ANSYS Workbench, (5) remote finite element calculation, namely completing remote finite element analysis on the parts by controlling a collaborative simulation environment by use of a command stream, (6) finite element analysis result feedback, namely realizing three-dimensional visual feedback of the finite element analysis results by use of WebGL technology, and (7) public service platform implementation.
