Weird free edges

[Bardagola]

Hello!

Firstly, I would like to congratulate the team behind flow5 and xflr5 for their great work putting out these programs as well as keeping them updated and thank you for making flow5 an open source software!

Regarding my issue, I'm trying to model a learjet 23 on flow5 having previously modeled it in xflr5 with no fuselage while getting good results (nice CL slope and polar shape) besides a slight shift to the left in the polar which I assume is due to a smaller CD0 since there's no fuselage.
Now, with flow5, I've built a fuselage, and the results are not I was expecting from it, a big decrease in the CL slope and actually less drag, I see an increase in the CD0 but still not satisfactory. I've followed all the recommended steps for modeling a plane and there's something strange happening I think: from what I can tell from the documentation, the only free edges shoul be located at the trailing edges and wing tips, however, my model presents no free edges in the tips, instead, I'm getting them in the interfaces between the fuselage and the wings/fin, as you can see in the picture below, I even tried aligning the wings nodes with the fuselages nodes but it doesn't do anything.

I'm not sure the results not being what I was expecting is due to this or even if this is an impactful issue but I think it's a good starting point in my evaluation process.

Thank you in advance!

The free edges are not a big concern. It would be better for the meshes to be connected for the evaluation of local pressures, but these evaluations are unreliable anyway. I tried to explain this in video playlist on recommended parctices. The online written doc will catch up. Make sure that in the plane analysis, the option to include fuselage pressure forces is unchecked.

I am a bit more concerned by the look of the fuselage mesh. There seems to be two ovelapping meshes., but maybe it's just the image.

Other recommendations:
It is more imporetant to have higher panel densities on the wings than on the fuselage.
Prefer thin surface assembly
Make sure that elevator and fin do not intersect
