Following the steps in the “Foils in Flow5” video I have exported a series of foils to XFLR5 (blue downward arrow). XFLR5 opens with empty polars displayed, but no matter which of the exported foils I select from the dropdown, when I choose Analysis -> Multi-threaded Batch Analysis nothing happens, i.e., the analysis settings window does not open as it does if I use the sample model?

Could you please share the .xfl temporary project file? Its path is shown in XFLR5’s menu “File/recent files”.
Please send it to the contact address I sent you earlier.

The problem is that for historical reasons XFoil is limited to foils with less than 300 points. There is no such limitation in flow5, so that the export can cause an incompatibility. The foils are currently defined with 500 points. You’ll need to re-panel the foils (F3) to reduce the number.
I’ll add a warning in flow5 to alert the user.

On a side note, 100 to 150 panels is usually quite enough for XFoil to produce acceptable results in a reasonable time.
