 where RHS are the other right-hand side terms. The parameters to be set by the user are - `A` is the sponge amplitude, `n` is the sponge strength and the `Q_\mathrm{target}` - the target solution in the sponge. `\xi` is a linear coordinate that is 0 at the beginning of the sponge and 1 at the end. An example of the sponge inputs can be found in ``Exec/RegTests/Terrain2d_Cylinder``.
