abaqus 使用技巧-Inp文件中单元类型改变时，一定要注意，划分网格的时候是否，选用了一种望各类型，比如4变形和3变形的区别，如果用注意将所有的单元类型都做相应的修改。这说明单元类型由2个因素决定，1网格形状，2计算任务.(Abaqus tips-When changing the unit type in the Inp file, be sure to pay attention to whether or not to select a type, such as 4 deformation and 3 deformation, if you use the attention, all the unit types should be modified accordingly. This shows that the unit type is determined by two factors, 1 grid shape, 2 calculation tasks.)
