在划分计算网格时，采用了混合网格生成技术，并对细小的结构进行了网格的局部细化。
Mixed gridding technology is applied at gridding drawing process, and the gridding of small structure is minished.
它包括把地球表面划分为一个有细小网眼的网状区域。
最后对有限元分析误差进行评估及原因分析，并得出有限元分析计算时网格划分并不是越细小越好，关键是＂适度＂的结论。
So a conclusion that the mesh is not the smaller the better when you analyze through FEA is educed, the key point is to choose a proper mesh size.
