A DUAL LEAST-SQUARES FINITE ELEMENT METHOD FOR LINEAR HYPERBOLIC PDES: A NUMERICAL STUDY

, 2008
. In this paper, we develop a least-squares finite element method for linear Partial Differential Equations (PDEs) of hyperbolic type. This formulation allows for discontinuities in the numerical approximation and yields a linear system which can be ...

Extrapolation Techniques For Constructing Higher Order Finite Element Methods

, 1993
. The p-version of the finite element methods requires the exact calculation of the stiffness matrix by a special form of numerical integration. As an alternative to classical techniques that are based on Gauß quadrature, we propose to use low order ...

Low-Complexity Finite Element Algorithms for the De Rham Complex on Simplices

, 2014
. We combine recently-developed finite element algorithms based on Bernstein polynomials [1, 14] with the explicit basis construction of the finite element exterior calculus [5] to give a family of algorithms for the Rham complex on simplices that ...
