Automatic Mesh Generation, Error Estimation, and Auto‐adaptation Technique
Zhu Bofang · 2018
Practical engineering structures are complex, so it may be troublesome to divide the computing grid and to input the node coordinates and loads manually. Therefore, it is necessary to establish an automatic mesh generation method, which means that if you divide the practical engineering structures into several subfields and input the corresponding data, then a detailed computing grid will be created by the computer and numerical values such as nodal coordinates and loads will be calculated automatically. This chapter presents the methods for automatic generation of computing grid. There are three ways to modify the computing grid: h mode, p mode, and mixed mode. The chapter also presents error estimation for a cantilever. According to calculation experiences, the module of error calculated by the approximate calculation multiplied by a correction factor k is more close to the module of error calculated by the exact calculation.
