Hello, I'm a bit surprised because so far xflr5 had compiled and run on all OS with Qt6 without a hitch. What was the error and how did you fix it? André

The interpolation of the viscous drag using the local apparent angle is less reliable than the interpolation based on the lift coefficient. The latter method is marked "recommended" and should be preferred. Also please keep in mind that there is no such thing as "ground truth" in xflr5 and flow5 given all the approximations made in the potential flow model and in the evaluation of the viscous drag using 2d data. In the future, please post all flow5 related questions on the flow5 project page. An...

upgraded XFoil-lib to v1.1 for compatibility with flow5

There won't be any new development for xflr5. In fact v6.62 is intended to be the last version before the project closes formally at the end of the year. Please consider upgrading to flow5 which can handle asymmetric configurations.

Hi everyone, v6.62 is intended to be the last version of xflr5, barring any new major bug which would need fixing. The plan is to close the project at the end of 2026. Please consider upgrading to flow5. All xflr5 features except for inverse foil design have been ported to the new application. André
