I have a problem running XFLR5 on my Macbook. I create a modell on my iMac and calculation worked well. I was able to calculate polars for different profiles. I coopied the xfl.file to my MacBook and tried repeat the calculation of the model. Instead a polar I got only one dot. The iMac is running under Monterey, on the MacBook I have installed Mojave. Can anybody help to solve the problem? Many thanks.

These problems seem to be caused by incorrect settings. To restore the default configuration, delete the .ini files
Windows: "C:\Users\your_user\AppData\Roaming\XFLR5.ini"
Mac: "/Users/your_user/.config/XFLR5.ini"
Linux: "/home/your_user/.config/sourceforge.net/XFLR5.ini"
The menu option "restore default settings" will not be enough; the .ini needs to be deleted.
Not sure why this occurs all of a sudden but it will be fixed in the next version.

Dear André,
many thanks for your help, everything works fine again. I spend a lot of time to find the reason for the problem and you saved me a lot of time!

Dear Andre,
I have another problem with XFLR5 I cannot fix. I am running XFLR5 on Mac. After open an airfoil and try to modify the relative thickness the program quits immediately. Is this a problem of the program or do I something wrong?

Most likely the airfoil format is wrong.
Airfoil name on the first line
Coordinates starting from TE to LE by way of upper surface and back to TE

Thanks for the quick reply. I took clarkY coordinates and controlled the data file as recommended. The profile was correct visible in the "direct foil design" module. X-foil calculation works and the results are plausible. When I tries to change the thickness it immediately quits. I am sure to use the correct data format. Any other suggestions

Hi Klaus,
I have this issue on the last update of Mojave as well, if I select the option from the drop down menu.
A workaround is to go to the Direct Foil Design module, right click on the airfoil and then select "scale camber and thickness" from the pop up menu instead.
Cheers,
Stefan

Hi Stefan,
thanks for your tip. It works that way.
