  DISPLAY
  In the following PHOENICS input file, the single-wave formulation
  is exemplified. The initial volume-fraction profile is made up
  of two straight lines; and the two fluids, of equal densities
  are given equal and opposite velocities. The predicted profiles
  certainly show that the irregularity of the profile increases
  in amplitude.

  A 1-second period is considered, divided into 100 equal intervals
  a duct of 1m length is considered, with 20 equal intervals.
  The initial velocities are 1.0 m/s, in opposite directions.
  The initial values of r represent a symmetrical shallow roof
  (or trough).
  The cyclic boundary condition is activated.

  PHOTON (Autoplot) commands are provided at the top of the Q1 file.
