A Posteriori Error Estimation of hp-dG Finite Element Methods for Highly Indefinite Helmholtz Problems
In this paper, we will consider an hp-finite elements discretization of a highly indefinite Helmholtz problem by some dG formulation which is based on the ultra-weak variational formulation by Cessenat and Deprés. We will introduce an a posteriori error estimator and derive reliability and efficiency estimates which are explicit with respect to the wavenumber and the discretization parameters h...
متن کاملGeneralized DG-Methods for Highly Indefinite Helmholtz Problems based on the Ultra-Weak Variational Formulation
We develop a stability and convergence theory for the Ultra Weak Variational Formulation (UWVF) of a highly indefinite Helmholtz problem in Rd, d ∈ {1, 2, 3}. The theory covers conforming as well as nonconforming generalized finite element methods. In contrast to conventional Galerkin methods where a minimal resolution condition is necessary to guarantee the unique solvability, it is proved tha...
متن کاملA stabilized DG-type method for solving efficiently Helmholtz problems
We propose a stabilized discontinuous Galerkin-type method (SDGM) for solving e ciently Helmholtz problems. This mixed-hybrid formulation is a two-step procedure. Step 1 consists in solving well-posed problems at the element partition level of the computational domain, whereas Step 2 requires the solution of a global system whose unknowns are the Lagrange multipliers. The main features of SDGM ...
متن کاملA Posteriori Error Estimation for Highly Indefinite Helmholtz Problems
We develop a new analysis for residual-type a posteriori error estimation for a class of highly indefinite elliptic boundary value problems by considering the Helmholtz equation at high wavenumber k > 0 as our model problem. We employ classical conforming Galerkin discretization by using hp-finite elements. The key role in the analysis is played by a new estimate of the Lerror by the error in t...
متن کاملhp-Analysis of a Hybrid DG Method for Stokes Flow
This manuscript deals with the hp error analysis of a hybrid discontinuous Galerkin method for incompressible flow. Besides the usual coercivity and boundedness estimates, we establish the inf-sup stability for the discrete incompressibility constraint with a constant, which is only slightly sub-optimal with respect to the polynomial degree. This result holds on irregular and hybrid meshes in t...
