%% Create a new instance of the XFOIL class, and set some properties

xf.Visible = true;    % Set it to false to hide XFOIL plotting window

%% Create a NACA 5-series airfoil
xf.Airfoil =  Airfoil.createNACA5('23012',150);
% To create a NACA 4-series, use   >> xf.Airfoil =  Airfoil.createNACA4('0012');
% To load an existing airfoil, use >> xf.Airfoil =  Airfoil('naca0012.dat');

%% Setup the action list


%Add five filtering steps to smooth the airfoil coordinates and help convergence
xf.addFiltering(5);

%Switch to OPER mode, and set Reynolds = 3E7, Mach = 0.1
xf.addOperation(3E7, 0.1);

%Set maximum number of iterations

%Initializate the calculations

% %Calculate a sequence of angle of attack, from 0 to 25 degrees, step size of 0.1 degrees

%for alpha = 0:0.1:25
%    xf.addAlpha(alpha);
%    xf.addActions(sprintf('CPWR alpha_%f.txt',alpha));
