DISPLAY
This case concerns the steady flow of a fluid heated from below
and cooled at the top. At the prescribed Rayleigh number a steady
state can be attained, but this may not be so at higher Rayleigh
numbers, because the flow is essentially unstable.
XCYCLE is true, so the flow is free to have a convection-cell size
which differs from that of the width ot the integration domain.
The conjugate-gradient solver is used.
The Q1 contains PHOTON USE commands.
