- * In older versions of the library (prior to 8.2), if you wanted also

- * the purposes of mesh refinement, you could call
- * Triangulation::set_boundary to associate a boundary object with a
- * particular boundary indicator. This method is still supported, and
- * it allows the Triangulation object to use a different method of
- * finding new points on faces and edges to be refined; the default is
- * to use a FlatManifold object for all faces and edges. The

- * The suggested method from version 8.2 onwards, is to split the
- * geometrical description of the boundary from its physical meaning,
- * by using separately manifold_ids and boundary_ids. The former are
- * used to describe how the geometry changes, and the latter are used
- * to identify the boundary conditions.

* Many of the functions in namespaces DoFTools and VectorTools take
* arguments that specify which part of the boundary to work on, and

* In a sense, this approach to serialization means that re-loading a
