  The problem considered is 2D supersonic flow in a 'supersonic
  diffuser', i.e. a converging duct. The problem is solved using
  the IPARAB=4 option of the parabolic solver. The flow enters
  axially at MACH 2, and then passes over a 8o corner where a weak
  oblique shock wave is generated of angle 37o, which is in turn
  reflected from the bottom of the duct to arrive at the top corner
  of the exit plane. The PHOENICS results are compared with the
  results of shock theory below:

                M1    M2    M3   |  P1/Po1   P2/Po1  P3/Po1
    Theory     2.0   1.71  1.42  |  0.128    0.197   0.293
    PHOENICS   2.0   1.75  1.45  |  0.128    0.192   0.293

  Here, M, P and Po denote Mach number, static pressure and total
  pressure, respectively; and 1, 2 and 3 denote inlet, post
  shock, and post reflected-shock, respectively.
