Hi,
I am using Anaconda3 and I installed Aeropy. When I try the sample code:
from aeropy.xfoil_module import find_coefficients find_coefficients(airfoil='naca0012', alpha=12.)
I got this error:
runfile('C:/Users/x/untitled2.py', wdir='C:/Users/x')
Traceback (most recent call last):

FileNotFoundError: [WinError 2] Impossibile trovare il file specificato

How can figure it out?
Best
