  1. New: There is now a new Triangulation<dim>::prevent_distorted_boundary_cell 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 prepare_coarsening_and_refinement. Therefore this + should have no effect on user codes. +
