    The geometry of this case is a rectangular  vessel  with
    two-padlle   impellor  inside.  There  are  therefore  2
    velocity components.

    The vessel is filled with the liquid  initial  state  of
    which is characterized by difference in concentration of
    inert contaminant:  the upper part of the vessel is pure
    liquid while lower part concentartion is equal to unity.

    The paddle is supposed to be suddenly set in rotation.

    The computational   task   is  to  predict  the  mixing,
    represented by the subsequent distributions of velocity,
    pressure and time-average concentration.

    PHOTON use commands are supplied.
