Prandtl-Meyer expansion wave solver

Numerical solution of a Prandtl-Meyer expansion wave flow field based on Anderson's CFD book

This program solves the Prandtl-Meyer expansion wave problem by using the MacCormack's predictor-corrector technique, as described in the book "Computational fluid dynamics: the basics with applications" from J.D.Anderson. As a result, this code might be useful for those trying to solve the problem, but also for anyone who is interested in supersonic aerodynamics.
