计算机辅助设计软件能否替代传统的设计计算方式？
现在众多大型的计算机辅助设计软件，是不是就可以说，设计者就可以不用类似手工的方法来进行力学分析，力学计算了？手工计算的确很复杂而且不精确。
谢谢。

不一定吧。
张老师有何看法？我也想知道。谢谢。

I don';t think that FEA software will replace the hand calculation completely. FEA can be used only if you have a 3D model. However, a lot of calculations need to be done before those models are built. Therefore, during the preliminary design stage, you still need to use hand calculations.
On the other hand, FEA is not an acurate solution. The boundary conditions and the model simplifications affect the results significantly. In most of cases, the results of FEA still need to be checked using hand calculations if they are too far to the hand calculation results.
Hope above information will give you a clarification about this quesiton.

Thank you very much！
Frankly I almost forgot everything about manual calculating.
