工程中有限元网格生成技术的研究和应用

Research and Application on Finite Element Mesh Generation Technique in Engineering

有限元网格生成是工程科学与计算科学相交叉的一个重要研究领域,文中简要综述了二维、三维网格生成算法。通过工程实例分析了目前工程中有限元网格生成技术应用情况,讨论了土木、水利工程中网格结点重复编号、施工过程中结点优化、随机投放骨料等特殊问题的网格特点及其处理方法。文中给出了较多的工程有限元网格实例以供借鉴。

The finite element mesh generation technique in engineering is a crossed research domain between engineering science and computation science. The universal 2D and 3D mesh generation methods are simply summarized. By engineering examples, the mesh application is analyzed based on the generation methods. For some especial civil and hydraulic engineering problems such as the reduplicate node numbering, the optimization of node number in construction and stochastic putting in concrete, the mesh characteristics and treatment methods are discussed. Some examples of engineering meshes are offered for reference.
