  • A simple shock-capturing technique for high-order discontinuous Galerkin methods 

    Huerta, Antonio; Casoni Rero, Eva; Peraire Guitart, Jaume (2012-08)
    Article
    Open Access
    This article presents a novel shock-capturing technique for the discontinuous Galerkin (DG) method. The technique is designed for compressible flow problems, which are usually characterized by the presence of strong shocks ...
  • Distortion and quality measures for validating and generating high-order tetrahedral meshes

    A procedure to quantify the distortion (quality) of a high-order mesh composed of curved tetrahedral elements is presented. The proposed technique has two main applications. First, it can be used to check the validity and ...
  • High-order mesh generation on CAD geometries

    We present a technique to extend Jacobian-based distortion (quality) measures for planar triangles to high-order isoparametric elements of any interpolation degree on CAD parameterized surfaces. The resulting distortion ...
  • One-dimensional shock-capturing for high-order discontinuous Galerkin methods 

    Casoni Rero, Eva; Peraire Guitart, Jaume; Huerta, Antonio (2012-02)
    Article
    Open Access
    Discontinuous Galerkin methods have emerged in recent years as an alternative for nonlinear conservation equations. In particular, their inherent structure (a numerical flux based on a suitable approximate Riemann solver ...
  • Optimization of a regularized distortion measure to generate curved high-order unstructured tetrahedral meshes 

    Gargallo Peiró, Abel; Roca Navarro, Xevi; Peraire Guitart, Jaume; Sarrate Ramos, Josep (2015-08-03)
    Article

    We present a robust method for generating high-order nodal tetrahedral curved meshes. The approach consists of modifying an initial linear mesh by first, introducing high-order nodes, second, displacing the boundary nodes ...
