DISPLAY
A heavier saline solution lies below a lighter fresh-water layer.
Both have the same temperature, and are at rest.
The lower fluid is heated, for a limited period. It becomes light$
er
than the upper fluid, and therefore rises through it.
However, after some time it sinks again because it loses heat
much faster than it loses salt.
The phenomena are described in the lecture which may be seen by
clicking here.$
The setting IDISPA=1 ensures that a parphi (or parada) file is
created enabling the development in time to be viewed by way of
PHOTON, with the z-axis being used for time.
A PHOTON USE file is supplied.
