Differentiable monotonicity-preserving schemes for discontinuous Galerkin methods on arbitrary meshes
Badia, Santiago; Bonilla de Toro, Jesús; Hierro Fabregat, Alba (2017-06)
Article
Accés obertThis work is devoted to the design of interior penalty discontinuous Galerkin (dG) schemes that preserve maximum principles at the discrete level for the steady transport and convection–diffusion problems and the respective ... -
Finite element solvers for hyperbolic problems
Hierro Fabregat, Alba (Universitat Politècnica de Catalunya, 2012-11)
Projecte Final de Màster Oficial
Accés obertIn this work we analyse and develop shock capturing (SC) techniques to improve the behaviour of one dimensional Finite Element methods for nonsmooth solutions. After investigating the state-of-the-art of the current SC ... -
Monotonicity preserving shock capturing techniques for finite elements
Hierro Fabregat, Alba (Universitat Politècnica de Catalunya, 2016-11-28)
Tesi
Accés obertThe 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 obertThe 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 obertThe 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. ...
