abstract = {<p style="text-align: justify;">We prove in an abstract setting that standard (continuous) Galerkin finite element approximations are the limit of interior penalty discontinuous Galerkin approximations as the
penalty parameter tends to infinity. We apply this result to equations of non-negative characteristic
form and the non-linear, time dependent system of incompressible miscible displacement.
Moreover, we investigate varying the penalty parameter on only a subset of a triangulation and the
effects of local super-penalization on the stability of the method, resulting in a partly continuous,
partly discontinuous method in the limit. An iterative automatic procedure is also proposed for
the determination of the continuous region of the domain without loss of stability of the method.</p>},
