   This problem  is  concerned with the prediction of lateral phase
   distribution for a bubbly flow in a duct. The phase distribution
   is  caused  by  the interaction of gravity and lift forces.  The
   latters  are  introduced  by  PLANT  options.  The   interesting
   variants  include  the changing in gravity directions to see how
   the bubbles accumulate near the walls for the upflow  situation,
   while  they  accumulate near the center of the duct for the down
   flow case.  Note that some uderrelaxation adjustments  could  be
   used to accelerate the convergence.
