subprocess issue #13

Open benoitpaillard opened 5 years ago

benoitpaillard commented 5 years ago

Hi all,

I'm getting the crash

AttributeError: module 'subprocess' has no attribute 'STARTUPINFO'

when running

find_coefficients(airfoil='naca0012',alpha=12.)

Any idea ? Thanks !

Based on a quick Google search, I found the reason here. STARTUPINFO is only available in Windows. If you are using Linux OS, comment that line and rerun it.

Hopefully, it works

I've found the best way is to replace the ps declaration in xfoil_module.py to " ps = sp.Popen(['/path/to/xfoil'], stdin=sp.PIPE, stdout=sout, stderr=None, encoding='utf8')" if you are using macOS or Linux
