It is a free program that enables you to perform airfoil analysis.
JavaFoil is a free program that enables you to perform airfoil analysis. the program takes a set of airfoil coordinates, it calculates the local, inviscid flow velocity along the surface of the airfoil for any desired angle of attack. It also solves a set of differential equations to find the various boundary layer parameters.
The very best CFD program ever!
Very easy to handle everything
A very useful Windchannel Simulator!
