Abstract
A method is provided for generating a quadrilateral mesh and a hexahedral mesh. First, a geometric model, which is an object of meshing, is input. The model is either two-dimensional or three-dimensional. Multiple bubbles of a plurality of types are generated in a region of the geometric model. The bubbles are moved according to an interbubble force defined by a predetermined rule, and the bubble count is controlled to adjust a neighboring relationship between the bubbles, so that the stable allocation of the bubbles are determined. By connecting the centers of bubbles of a specific type, a mesh is generated.
