Demonstration case for three region coupling with film consisting of an
aluminium panel with surface film running down forming rivulets in a box of air
which moved due to buoyancy with 6-way thermal and velocity coupling between the
panel<->film<->air<->panel. The case runs serial and parallel with arbitrary
decomposition.
Currently extrudeToRegionMesh does not directly support three region coupling so
foamDictionary is used to edit the of the boundary files of box and film regions
to add box<->film coupling.
