  FREE SURFACE EXAMPLES - Slumping of a column of liquid
                               HOL method

  2-dimensional (y-z), Cartesian, transient, elliptic simulation

  This case simulates the slumping of a  liquid column that
  may arise, for example, when container walls break down.
  In addition an obstacle can be errected in the path of the liquid.
