基于形状识别技术和边界拟合方法，开发了一个通用的六面体网格自动生成系统。在该系统中，实体模型被分析和分解成单连接的子模型。然后，其他子模型拓扑结构相同的原始的构造只使用正交角。立方体用于构建中间模型，中间模型重新组装这些立方体，最后，通过将立方体映射回原始实体模型来生成六面体网格。
A general-purpose automatic hexahedral mesh generation system for FEA (Finite Element Analysis) was developed based on a shape recognition technique and the boundary-fit method. In this system, a solid model is analyzed and decomposed into single-connected sub-models. Then, other sub-models topologically identical to the original ones are constructed using only orthogonal angles. Cubes are used to construct intermediate models, which reassemble these, and finally, hexahedral meshes are generated by mapping the cubes back onto the original solid model.
