楼主，你好，看了你写的教程收益匪浅，现在我遇见这样的问题，情况是这样的：
In Analysis 'Flow Analysis 1': The ANSYS solution units defined in the input file via the /UNITS,MPA command differ from the current CFX solution units. All
necessary unit conversions will be applied to data transfers between the solvers.
应该是单位的问题吧，但是我的单位都是一样的呀，实在不知道该怎么办了，关键是解算的时候就报错了
