We have developed a knowledge-based system for automatically generating two-dimensional meshes, which is easily applicable to various fields of computational dynamics with structured meshes. We analyzed and modeled experts' mesh generation procedures in the simulation processes of forging deformations, vehicle aerodynamics and engine in-cylinder flows. This paper outlines the mesh generation system focusing on the implementation techniques of search and inference, and then shows the functional ability of this system applying to the forging simulation. The characteristics of this system are as follows. (1) Plural solutions can be efficiently obtained at the same time in the search phase, using the global dependency and local dependency. (2) The meta-level inference method and its knowledge representation method are very applicable to various fields of analyses. In the rigid-plastic deformation analysis, remeshing is needed. We have applied this mesh generation system to forging simulation, and found it promising for practical use. It was clarified that appropriate sub-region shapes and meshes in the deformed workpiece were generated at each stroke.
