Hi Stefan, Thank you very much for your detailed response and for taking the time to clarify this. I understand that the VLM method is an idealized representation, and the differences can indeed fall within its numerical tolerance. However, in my case, what I’m changing is the tilt angle of the wing — which is essentially equivalent to changing the angle of attack. Since I’m only analyzing the wing (without tail or fuselage effects), I would expect that the lift coefficient (Cl) of the aircraft with...

Dear XFLR5 Team, I hope this message finds you well. I would like to ask for your technical clarification regarding a situation I encountered while performing VLM analyses in XFLR5. Before starting the analyses, I defined different tilt angles on the same wing geometry and carried out three separate analyses. All other parameters — such as airfoil, mesh configuration, and analysis settings — were kept completely identical across all cases. Based on the difference between the applied tilt angles,...
