The following cases concern the calculation of the temperature
field within and around several metal plates and blocks, over
which and around which air is flowing. The conductivity of the
metal is supplied by the field named PRL, the information for
is transferred to EARTH via the GREX-called subroutine GXPRL.
The geometry and flow are depicted diagramatically below:

Solution for the air-flow is performed first in isolation from
the heat-transfer problem: all of the different heat-transfer
cases are based upon this flow-field. The flow-field, once
obtained, is frozen, and the heat-transfer problem is solved.
Users might find it instructive to try varying the inlet
velocities, and thereby vary the amount of cooling or heating of
the plates and blocks by the air. In particular, reduction of UIN
will cause BLOCK1 to become much hotter. Similarly, the strength
of the heat sources, their location, and the conductivities,
heat capacities and densities of the plates can be adjusted
to produce rather different problems. Imperfect contact between
the plates and blocks might be simulated by introducing the
relevant surface porosities with values less than one in
appropriate places.
