Techniques of Two-dimensional Finite Element Mesh Generation for Complex River Ways

摘要

Due to the complexity of natural river ways and requirements for calculation accuracy,how to generate two-dimensional finite element mesh is very important.Based on Platform SMS 8.1,this paper takes the complex river way i.e.Fengtai Bridge-Tianjia'an as example to elaborate on the lead-in of terrain data and methods of automatic generation of adaptive meshes,and establishes a foundation for the following hydraulic calculation.
