The bounding box scaling controls can be used to create interesting meshes like
the $36^d$ cell mesh shown in Fig. \ref{fig:strong-scaling}. This mesh was created with 9 outside cells
on the left side and 12 ranks per dimension. The mesh

The same mesh refined by a factor $3^i$, $i \leq 1$ can be constructed if $3^i \times 9$ bounding box outside cells
are placed to the left of the domain.
The $36^d$ mesh requires a maximum-mesh-size of $\frac{1}{36} \approx 0.03$.
The uniformly refined variants must scale this mesh size with a factor $\frac{1}{3^i}$.
