That depends on the grid manager. UGGrid and AlbertaGrid will ensure
that<br>
automatically, ALUGrid will not (and that's not a bug).<br>

You have to iterate over the elements (the codim-0 entities) of the<br>
LeafGridView. For each element that you want to refine, call
grid.mark(1,<br>
elem). Once Iteration is done, call grid.preAdapt(), grid.adapt(), and<br>
grid.postAdapt(). Repeat until you are satisfied with the grid.<br>
<br>
If you know a priori that a certain element can be refined n times
uniformly,<br>
you can also tell that to grid.mark() by calling grid.mark(n, element)<br>
instead.<br>
