  • HDG-NEFEM with degree adaptivity for stokes flows 

    Sevilla Càrdenas, Ruben; Huerta, Antonio (2018-02-07)
    Article
    Open Access
    The NURBS-enhanced finite element method (NEFEM) combined with a hybridisable discontinuous Galerkin (HDG) approach is presented for the first time. The proposed technique completely eliminates the uncertainty induced by ...
  • Numerical integration over 2D NURBS-shaped domains with applications to NURBS-enhanced FEM 

    Sevilla Càrdenas, Ruben; Fernández Méndez, Sonia (2011-10-03)
    Article
    Open Access
    This paper focuses on the numerical integration of polynomial functions along non-uniform rational B-splines (NURBS) curves and over 2D NURBS-shaped domains, i.e. domains with NURBS boundaries. The integration of the ...
  • Tutorial on Hybridizable Discontinuous Galerkin (HDG) for second-order elliptic problems 

    Sevilla Càrdenas, Ruben; Huerta, Antonio (Springuer International Publishing, 2016)

    The HDG is a new class of discontinuous Galerkin (DG) methods that shares favorable properties with classical mixed methods such as the well known Raviart-Thomas methods. In particular, HDG provides optimal convergence of ...
