It also challenged them. Why were their calculations of aerodynamic forces so often out?

这也对他们提出了挑战。为什么他们对空气动力的计算经常出错？

Simulating the pressure distribution and aerodynamic forces is a large topic, however, visualizing these results is at least as well-studied and difficult as writing a simulator.

模拟压力分布和空气动力是一个大主题，然而，将其结果可视化基本上跟编写出一个模拟器一样困难，且需要充分的研究。
