> +Each coarse grid element can be given a parametrization that describes an
> +embedding into physical space. This does not influence the grid itself
> +-- elements of a <kbd>FoamGrid</kbd> are always affine.
> +However, when refining the grid, the new vertices are determined according
> +to the parametrization.
> +That way, the grid approaches the shape described by the parametrization
> +functions more and more as it gets refined:

> +<p>
> +As a unique feature of a <kbd>dune-grid</kbd> implementation, a
> +<kbd>FoamGrid</kbd> is allowed to grow and shrink, i.e., elements can be added
> +to or removed from the grid at runtime. Data attached to the grid is not
> +invalidated by this. This allows to simulate problems with growing and shrinking
> +domains, which is useful for various network growth and remodeling problems:
