+As we expected, the convergence order for each of the different

+interesting, though, is that the error for a bilinear mapping
+(i.e. degree 1) is more that three times larger than that for the
+higher order mappings; it is therefore clearly advantageous in this
+case to use a higher order mapping, not because it improves the order
+of convergence but just to reduce the constant before the convergence
+order. On the other hand, using a cubic mapping only improves the
+result further insignicantly, except for the case of very coarse
+grids.
