Thread Subject: Potential Flow Analysis Code Help

I need to create a contour plot of streamlines over a spinning cylinder. I havethe equation: Y=(V*R*sin(theta))*(1-R^2/r^2)+(gamma/2*pi)log(r/R)
I am having trouble plotting this function as a contour plot where the streamlines are a constant Y. Any help regarding contour plots would be greatly appreciated. Thanks in advance, Brian.

Seems pretty straightforward to me.
Show us what you've tried that does not work.
