Question: Modeling of inviscid fluid flow around Joukowski airfoil

Hi maple users

I'm about to do an assignment on the Joukowski transformation, where I have modelled and airfoil resembling the NACA-64015 airfoil. The parameters of the circle in z-plane are as follows: r=1.1241, x=-0.1241, y=0.0, where r is the radius of the circle, and x and y is the parameters used to offset the center of the circle. The problem is that I can't seem to plot the airfoil with contuours showing the fluid flow. I would therefore like to know if any of you guys has solved this before? Any help is much appreciated.
