Hello!I'm a beginner of Ansys fluent and need some advice.
I am doing my course project and simulating a cruising aircraft, and finally i get a reasonable contour with unreasonable lift and drag. I want to know what is wrong with it. The mach number is 0.85 and the height is 10Km.
The contours and the forces is in the following picture.
I would be appreciated if someone gives me any advice. Have a good day.
P.S. Some expressions could be weird since it's not my native language. Please understand.
