A layer of liquid lies above a second layer of sligtly smaller
density. The initial surface is not quite horizontal (effected
by introducing a small gravity-related momentum source into the
The representation is two-dimensional. The density is calculated
from the enthalpy, by postulating a steep enthalpy-density
dependence, modified by maximum and minimum limits.

The x-y plane is used, so that fields for all time steps can be
dumped to a single phi file (called parphi) and viewed by PHOTON.
The setting IDISPA=1 effects this. The PHOTON commands are
supplied.
