Python Airfoil Tools

Ubuntu:

• Download and extract Xfoil binaries from here

  • Test that you can run XfoilFixed/bin/xfoil
  • You might need to downlaod Fortran sudo apt-get install libgfortran3)

• Put the path to xfoil around 215 of ffdFoil.py (or put a link somewhere nicer, etc.)

Mac:

• Download Xfoil binaries here.

• Extract where you want and put the path to xFoilPath at around line 215 of ffdFoil.py

if you get an error that looks like this:

dyld: Library not loaded: /usr/local/opt/gcc/lib/gcc/9/libgfortran.5.dylib
  Referenced from: /Users/gaiera/Code/pyAFT/xfoil/Xfoil/./xfoil
  Reason: image not found

there might be some linking problems to your fortran libraries. you can try your luck at building from source, or just create a softlinks to your fortran library:

• Install gfortran (brew install gfortran)
• Create directory structure and softlinks as below:

create a soft link to where it is supposed to be: ln -s /usr/local/opt/gcc/lib/gcc/9/libgfortran.5.dylib /usr/local/gfortran/lib/libgfortran.5.dylib

(/usr/local/gfortran/lib/libgfortran.5.dylib is where it comes from brew, but locate libgfortran will give you some options you might have installed along the way with conda, scipy, or something like that)

(note: you might have to make the whole directory structure too)

You will have to do it for libquadmath too: locate libquadmath.0.dylib (gives, /usr/local/gfortran/lib/libquadmath.0.dylib) ln -s /usr/local/gfortran/lib/libquadmath.0.dylib /usr/local/opt/gcc/lib/gcc/9/libquadmath.0.dylib

• Now you should be able to go to where Xfoil is extracted and type ./xfoil and it should run
