N2 - A simple and efficient optimization scheme for second-order Whitney elements using appropriate material-dependent geometric transformations is introduced. A remarkable improvement of convergence is observed, especially when it comes to ill-conditioned linear systems. Such a scheme can be considered a kind of geometric preconditioning that not only provides an optimally-conditioned approximation but is also open to further improvements.
