Good evening, gentlemens. I would like to express my gratitude for your work.
I am here to ask a question. If you think my approach is flawed, please let me know.
I am conducting a study on the behavior of a cargo UAV during a specific timeframe of the transition regime. For this study, I created a model consisting of a wing, a tail, and four lifting propellers. I would like to see the pitching moment on the entire UAV for the above-mentioned case. However, the column with all moments is empty in the .history file. Is it possible to obtain the moments of the entire UAV with this formulation of the problem?
I have also attached a test case.
Thank you in advance!

I think that I can use Cmy for the whole plane = Cmy from "_DegenGeom.group.1" file +
Cmy from
"_DegenGeom.group.2" file +
Cmy from
"_DegenGeom.group.3" file
Am I right?

Where:
_DegenGeom.group.1 - wing and tail
_DegenGeom.group.2 - front prop
_DegenGeom.group.1 - wing and tail
_DegenGeom.group.2 - front prop
_DegenGeom.group.3 - rear prop
