A posteriori error analysis of hybrid higher order methods for the elliptic obstacle problem
Kamana Porwal, Ritesh Singla
In this article, a posteriori error analysis of the elliptic obstacle problem is addressed using hybrid high-order methods. The method involve cell unknowns represented by degree-$…
Supremum-norm a posteriori error control of quadratic discontinuous Galerkin methods for the obstacle problem
Rohit Khandelwal, Kamana Porwal, Ritesh Singla
We perform a posteriori error analysis in the supremum norm for the quadratic discontinuous Galerkin method for the elliptic obstacle problem. We define two discrete sets (motivate…
Adaptive quadratic finite element method for the unilateral contact problem
Rohit Khandelwal, Kamana Porwal, Tanvi Wadhawan
In this paper, we present and analyze a posteriori error estimates in the energy norm of a quadratic finite element method for the frictionless unilateral contact problem. The reli…
Pointwise A Posteriori Error Analysis of a Discontinuous Galerkin Method for the Elliptic Obstacle Problem
Blanca Ayuso de Dios, Thirupathi Gudi, Kamana Porwal
We present a posteriori error analysis in the supremum norm for the symmetric interior penalty discontinuous Galerkin method for the elliptic obstacle problem. We construct discret…
Adaptive finite element method for an elliptic optimal control problem with integral state constraints
