  DISPLAY
    A simple case to demonstrate the effect of thermal
    diffusion on the fields of H2 (in C1) and N2 (in C2).
    The when the temperature gradients are positive, the
    thermal diffusion acts against the bulk mass-flux and
    acts to establish a negative gradient in H2 in the
    cross-flow direction. When the temperature gradient
    is reversed, the thermal diffusion acts with the bulk
    mass-flux causing the overall values of H2 to be smaller
    and a positive gradient to be established in the cross-
    flow direction.
