We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

为何adjoint中通过observable value 读出来的pressure drop与通过surface integrals 得到的压降不一样?

      如下图所示,采用如下方法得到的压降,为何二者不一样?

      伴随求解给的是总压差,而上图方法2计算的是静压差,而且是基于质量平均的静压差。应该读取基于面积平均的总压差,这样二者就吻合的很好了,如下图。
