However, the development of p or hp adaptive strategies for mixed formulations presents a challenge in terms of code complexity for the construction of Hdiv basis functions of high order on non-conforming meshes, and compat… text/html 2015-10-19T08:33:50-03:00 http://www.labmec.org.br/wiki/publicacoes/report/tiago-forti?rev=1445250830&do=diff A comparative numerical study of different finite element formulations for 2D model elliptic problems: continuous and discontinuous Galerkin, mixed and hybrid methods Abstract In this work, different finite element formulations for elliptic problems are implemented and compared, in terms of accuracy versus number of required degrees of freedom. The implemented formulations are: a) the classical H discontinuous Galerkin formulation by Baumann, Oden and Babuska; b) a mixed discontinuous Galerkin…
