Hi everyone,

My model attached here looked like asymmetric and I've deleted

one of fuselage sections.

Since that, clean build up for fuselage+Wing (without any fans) looks better now but

once I put fans back on, it turns out the same results come up,,

What do I do?

Is there anyone who's gonna be helping me out?

Literally I'm struggling,,

I ran the VSPAERO settings in the model for a single, zero alpha with disks and everything ran well enough.

What asymmetry are you referring to? Geometric or in the wing loading? You have disks turning the same direction on both sides of your wing so an aero imbalance is expected.

Also, your lifting rotors are turning at Mach 0.46. Is this really needed?

Check you solution in the Viewer to see if the pressure distribution and your wakes make sense. At the conditions provided, your wakes are all scrambled up.

Thanks for the answer,

Glad that it ran well enough,,
I set the diagonal direction to the same sign Like -1000 RPM, is that wrong? what do you mean by 'both sides' ?

and Mach 0.46 is too big??

It turns out there's gotta be sth wrong with AOA 9 °, with weird wakes, CDtot, L/D ,, even tho I set different values for Re, Mach

What do I do?
