  DISPLAY
  3-dimensional, Cartesian, steady, elliptic simulation
    This case calculates the accumulation of two groups of
    particles, of different diameters, along the bottom of
    a three-dimensional channel through which liquid flows
    from low z to high z. The particle slip velocities are
    normal to the primary flow direction.
    A blockage has been introduced in the middle of
    the flow region to complicate the flow situation.
    Plane ix=3 is the symmetry plane.
