当然也可以用一种简便的方法来处理这个问题。类似于2D Axisymmetric plain strain.
只用了一个单元, 这种方法比上面那种3D的要快,结果两者相似。
将分析结果贴出来。

Checking the model before creating elements...
These checks take into account the fact that AutoGEM will
automatically create elements in volumes with material
properties, on surfaces with shell properties, and on curves
with beam section properties.
Generate elements automatically.
Checking the model after creating elements...
No errors were found in the model.
