  DISPLAY

  The continuous phase has density =1.0. The influence of the
  second-phase density is demonstrated by making the following
  settings:
         IY    1       2     3     4     5
         RHO2  1000.0  500.0 250.0 100.0 50.0

  The 2D flow is converted to five independent 1D ones by fixing
  the y-direction velocities to zero.

  This device of using a "spare" dimension for showing the influence
  of a data-input parameter often saves time.

  The heavy-fluid density is made a function of y by initial-value
  settings of H2, with the option RHO2=LINSCAL (GRND1), which makes
  the second phase density a linear function of H2.

  Time-direction plots are made possible by setting IDISPA = 1.
