Structured Quad Mesh Generation of Curved Surfaces and Method of Locally Adding Mesh Density Based on Mapping Approach

有限元网格的自动生成,是建立有限元模型的重要技术.在现有的有限元网格划分技术中,结构化网格能自动生成形状和尺寸合理的有限元网格,并且易于实现网格的调整和细化.本文对基于映射法的曲面结构化四边形网格划分进行深入研究,详尽分析了相应的处理技术和算法,并且在网格后处理阶段,针对局部需要改进的网格提出了一种精化算法,并给出实例.

Meshing is an important technology for creating finite model.Among the methods of meshing,structured mesh can create rational dimension and good form meshes which are easily adapted and refined.This paper studies structured quadrilateral mesh generation of surface based on mapping approach,analyzes corresponding solution and arithmetic at large,and gives an arithmetic and an example for locally adding mesh density at phase of meshing post treatment .
