A modelling method, which generates a computational mechanics model, is suggested for mechanical design work. The design model is described by three kinds of data : geometric data, structural data, and product data. It is applied to generate the computational mechanics model automatically by the newly developed, extended quad/oct tree method for discretized mesh generation and numerical analyses data generation. The extended quad/oct tree method automatically generates suitable meshes for either FEM, BEM, or FDM. Suitable meshes mean that a fine mesh is generated where it should be and a coarse mesh is generated at areas outside the points of interest in the analysis. The data for problem specification in the analysis are translated from product data automatically and preserved with the quad/oct tree structure in order to inherit the data to the branches. The preserved data are utilized especially for an h-version of the remeshing process.
