Flow around arbitrary body Solver.

This matlab file solves the laplace equation of the stream function around an arbitrary body.

% Notes:
% 1) That this code SOLVES the flow over NACA 4-digit, Joukowski Airfoils and Cylinders.
% 2) This code solves the PDE: [[\psi_{xx} + \psi_{yy} = 0]] "where E is the Stream Function"
% 3) Number of nodes in x and y should be EQUAL.
% 4) The Grid used in this solution is a H-Grid .
% 5) The solver uses PSOR (Non-Updating) Scheme.
N.B.: After running the Flow Solver.m file it will requires to enter information about the body in the command window <Some thing like this>:
Enter "J" for Jokowski Airfoil , "N" for NACA Airfoils or "C" for Cylinder: 'J'
Enter The Airfoil max. Thickness/Chord and max. Camber/Chord as [t/c C/c]: [0.06 0.05]
Enter The Airfoil Chord Length: 1
Joukowski Airfoil: Thickness/Chord = 0.06
Camber/Chord = 0.05
Chord = 1
