    The main object of study of this thesis is the development of artificial diffusion shock capturing techniques for continuous and discontinuous Galerkin (cG and dG) approximations of the convection-diffusion problem. Special ...
  • On discrete maximum principles for discontinuous Galerkin methods 

    Badia, Santiago; Hierro Fabregat, Alba (2015-04)
    Article
    Accés obert
    The aim of this work is to propose a monotonicity-preserving method for discontinuous Galerkin (dG) approximations of convection–diffusion problems. To do so, a novel definition of discrete maximum principle (DMP) is ...
  • Shock capturing techniques for hp-adaptive finite elements 

    Hierro Fabregat, Alba; Badia, Santiago; Kus, Pavel (2016-09)
    Article
    Accés obert
    The aim of this work is to propose an hp-adaptive algorithm for discontinuous Galerkin methods that is capable to detect the discontinuities and sharp layers and avoid the spurious oscillation of the solution around them. ...
