Parameter definitions:
use_naca: logical, true if we want to generate a NACA 4/5 digit airfoil
internally, false if we should read the coordinates from the
UIUC database.
naca: integer NACA 4/5 digit number. Note, no error checking is
performed here to see if it s a valid number. that s done by the
perl-script that executes this code, so make sure you give it a
valid number.
airfoil: string, name of the database airfoil to read, including the
relative path-name.
smoothing: logical, true if you want to smooth the surface points that you
read from a file. Note, smoothing will alter the airfoil data,
however, unsmoothed data may result in ripples in the pressure.
npanels: integer number of panels for the simulations. If you want to use
more than 200, increase the value of ndim in the common.inc file
