The variety of phenomena possible in the seven parameter system defined by equations (2.52)-(2.55) and the geometry (fig. 5.1) is far too diverse to be adequately addressed here. Instead, a single case is presented in some detail. The parameters are: $\varPhi =0.69,\,\mbox{\textit{Gr}}(1+N)\mbox{\textit{Pr}}_r=10^{3},\,\mbox{\textit{Pr}}_r=0.71,\,\mbox{\textit{Pr}}_I=\mbox{\textit{Sc}}=0.61,\,N=0.5$ and $\mbox{$\mathcal A$}=5$, and the mesh used is that shown in figure 5.3. Figure 5.4 shows the solution variables.
