Detailed Description

template<int dim, int spacedim = dim>
class MappingBox< dim, spacedim >

A class providing a mapping from the reference cell to cells that are axiparallel, i.e., that have the shape of rectangles (in 2d) or boxes (in 3d) with edges parallel to the coordinate directions. The class therefore provides functionality that is equivalent to what, for example, MappingQ would provide for such cells. However, knowledge of the shape of cells allows this class to be substantially more efficient.

Specifically, the mapping is meant for cells for which the mapping from the reference to the real cell is a scaling along the coordinate directions: The transformation from reference coordinates $\hat {\mathbf x}$ to real coordinates $\mathbf x$ on each cell is of the form

\begin{align*} {\mathbf x}(\hat {\mathbf x}) = \begin{pmatrix} h_x & 0 \\ 0 & h_y \end{pmatrix} \hat{\mathbf x} + {\mathbf v}_0 \end{align*}

in 2d, and

\begin{align*} {\mathbf x}(\hat {\mathbf x}) = \begin{pmatrix} h_x & 0 & 0 \\ 0 & h_y & 0 \\ 0 & 0 & h_z \end{pmatrix} \hat{\mathbf x} + {\mathbf v}_0 \end{align*}

in 3d, where ${\mathbf v}_0$ is the bottom left vertex and $h_x,h_y,h_z$ are the extents of the cell along the axes.

The class is intended for efficiency, and it does not do a whole lot of error checking. If you apply this mapping to a cell that does not conform to the requirements above, you will get strange results.
