I know that you have to import the airfoil file as a dat file, but I am unable to on my mac book pro. I am wondering if anyone has had the same problem and have been able to fix it. On a windows, it is easy saved as a dat and uploaded into XFLR5 but i cant figure out what is going wrong on a mac. Any help would be nice.

I am having the mach number set at 0 so im not sure what is going wrong and why the program will not run the airfoil. I tried a different airfoil, but in the same series of GOE, but it is still saying the same error.

When trying to run the GEO433 airfoil, I keep getting the error of CpCalc: local speed too large, compressibility corrections invalid. I am not sure how to fix this as I have tried to change the Reynolds numbers. I have also trying creating more points in the polars but nothing seems to work. I have look at other responses online and they said to make sure the dat file that XFLR5 is pulling the data from is correct. I have checked this and am pretty sure this is correct. If anyone can help me fix...
