DISPLAY
This example is similar to that of case 170; but the
solution procedure is elliptic rather than parabolic.

Because the flow is nearly parabolic, economy is achieved by
not using the whole=field solver for scalars and by setting:

lithyd = 10, so that few sweeps are needed.

Further economies come from setting:

ISWC1 = LSWEEP and LITHC1 = LITHYD,

which entail that the scalars are solved only on the last sweep
and slab-wise iteration.

PHOTON commands are supplied.
