+                class="class">Triangulation&lt;dim&gt;</code>::<code
+                class="member">prevent_distorted_boundary_cell</code> function which is
+                only useful in case of anisotropic refinement. At the boundary of the
+                domain, the new point on the face may be far inside the current cell, if
+                the boundary has a strong curvature. If we allow anistropic refinement
+                here, the resulting cell may be strongly distorted, especially if it is
+                refined again later on. To prevent this problem, this function flags such
+                cells for isotropic refinement. It is called automatically from <code
+                class="member">prepare_coarsening_and_refinement</code>. Therefore this
+                should have no effect on user codes.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
