The following are the files and plot results of the two simulations I did.
2021.5.28(XZ).flair (3.8 KB)
2021.5.28（XZ）.inp (4.2 KB)
2021.6.7.1.flair (4.6 KB)
2021.6.7.1.inp (3.5 KB)
In the two plot results , one of them could see the geometric outline vaguely, and the other could not see the geometric outline at all.
What is the reason? How do I set Flair if I want to see a clear geometric outline in the image?
