Hello, everyone. I want to analyse a Airfoil, in this case the airfoil is e422, with a chord of 297 mm. The problem is that I cannot download this data (e422-il_100%.dat).
Thank you for your response. I intuitively understand what you are saying. But I don't understand how you found this error (or how you saw it).
I solved this problem after your answer, also intuitively, I copied from the wrong dat file to the correct dat file and the program ran it.
I don't know if there are other methods to solve this problem?
Unfortunately I have another problem. After successfully loading the data that I have already submitted, the program did not analyse it.
As I understand it, XFLR5 does not analyse wing profiles with chords of 1 to 100-200-300 mm and so on?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

I want to understand what I am doing wrong.
Thank you in advance for your answers.
The reason is that the end-of-line character used in your .dat file is "\r" instead of "\r\n" or "\n". It is not recognized by the Qt libraries.

To be more precise, the simulation is being carried out, but it has no answer.
