    • Adaptive hybrid discontinuous methods for fluid and wave problems 

      Giorgiani, Giorgio (Universitat Politècnica de Catalunya, 2013-04-02)
      Tesi
      Accés obert
      This PhD thesis proposes a p-adaptive technique for the Hybridizable Discontinuous Galerkin method (HDG). The HDG method is a novel discontinuous Galerkin method (DG) with interesting characteristics. While retaining all ...
