Notes

This function parses text files generated by DFDC (Ducted Fan Design Code) to extract geometric and performance data. It handles both the design point and off-design evaluation points.

The function attempts to read results for all combinations of Mach number, tip Mach number, and altitude. If a particular combination did not converge or the file is missing, the corresponding performance values are set to NaN and the converged_solution flag is set to False.
