We have L2_LAGRANGE basis functions, which are the same as the LAGRANGE basis functions but where dofs are associated with elements rather than the nodes, and hence can be discontinuous (hence the "L2" naming).

For > example, can I use a 4th order Lagrange interpolation on a quad4? You can do this with L2_LAGRANGE, though I think L2_LAGRANGE currently only goes up to third order (a patch that allows higher order would be welcome!) David
