Assume I want to performing an analysis for a model airplane with a wing and fuselage (tailless plane). The first case is that I am analysing the wing only, i.e. without the fuselage. Assume the wingspan is 2,00 meters. Everything fine in this case. Now I am including a fuselage in STEP-Format and cut out the wing sections. Assume the fuselage is 10cm wide at the position the wing is intersecting the fusalage. Furtheron the mesh between the wing and the fuselage is connected.
Now my question: How is the wing section inside the fuselage treated in the analysis? Do I need to extend the wingspan to 2,10 meters to have the same wing as in the first case, i.e. without fuselage? In both cases flow5 shows different MAC (mean aerodynimic chord) although the effective wingspan should be in both cases 2,00 meters. I am confused because the meshes of the wing and fuselage are connected, therefore I would assume that the wing section inside the fuselage is not taken into account for the analysis.
Thank you for any answer in advance.

Andre,
yes, this answers my question. Thanks for your support.

Hello,
The part of the wing inside the fuselage is ignored, if indeed the wing has been connected to the fuselage as you mention. Only the mesh is used in the analysis.
The reference dimensions are calculated as if the fuselage didn’t exist.
Hope this answers the question.
