The code computes the exact, inviscid compressible flow field with or without shock waves, and it uses a body oriented mesh to permit the exact treatment of an arbitrary body shape. The numerical integration employs the method of Godunov to obtain a stable finite difference approximation to the flow equations. Several examples of results of the code are included along with comparisons to wind tunnel data. (Author)
