Abstract:

- - In this work, adaptive concepts for the numerical solution of the wave - equation in inhomogeneous media are derived and applied to an example - taken from the physics of the solar atmosphere. The main focus is on ways - to estimate the error in the numerical solution with regard to arbitrary - functionals, i.e. quantities of interest, and the use of these estimates - for the generation of computational meshes best suited for the evaluation - of this functional. - -

- - Advantages and difficulties of this method are presented. In particular, - it is shown that the proposed approach is significantly better in many - cases than previous adaptive schemes not taking into account the quantity - of interest. Cases involving nonlinear functionals and in which the - approach fails, are presented along with theoretical explanations and - numerical evidence of the reasons for this. - -

- - The proposed methods are applied to a simple model from the physics of the - solar atmosphere and the propagation of linear acoustic waves is computed. - The fraction of the wave energy that passes the chromosphere-corona - transition is computed to good accuracy. -

Abstract:

- -

- Modern finite element software tends to become increasingly complex. - Techniques like adaptive meshes, error estimation, multigrid methods, or - hp finite elements require the programmer to work with extremely - complicated data structures and sophisticated algorithms. Designing programs - in a maintainable and expandable way while retaining run time efficiency has - therefore become a major task in applied numerical analysis. In our - experience, this task can only be fulfilled by using modern programming - languages and tools. -

- -

- We will show how modern aspects of the C++ programming language, in - particular templates, can be used to write algorithms for finite element - programs in a dimension-independent way. This enables us to test algorithms - in one or two space dimensions while using the same program for large scale - computations in three space dimensions as well. It will be demonstrated that - this is even possible without much loss in efficiency since tests for the - actual space dimension at run time can almost completely be avoided. -

- -

- The idiom above is one of several modern aspects of C++ used in the design - of the finite element library deal.II developed at the University - of Heidelberg. We will give a sketch of its implementation and examples how - it is used. -

Abstract

- - - In this paper, we present a super-convergence result for the Local -Discontinuous Galerkin method for a model elliptic problem on -Cartesian grids. We identify a special numerical flux for -which the L2-norm of the gradient and the -L2-norm of the potential are of order -k+1/2 and k+1, respectively, when tensor product -polynomials of degree at most k are used; for arbitrary -meshes, this special LDG method gives only the orders of convergence -of k and k+1/2, respectively. We present a series -of numerical examples which establish the sharpness of our theoretical -results. - - - - diff --git a/deal.II/doc/publications/2000/ckss.bib b/deal.II/doc/publications/2000/ckss.bib deleted file mode 100644 index 54a1a5f2c9..0000000000 --- a/deal.II/doc/publications/2000/ckss.bib +++ /dev/null @@ -1,20 +0,0 @@ - - - - - -

Local discontinuous Galerkin methods for the Stokes system

Abstract

- - -In this paper, we introduce and analyze local discontinuous Galerkin -methods for the Stokes system. For arbitrary meshes with hanging -nodes and elements of various shapes we derive a priori estimates for -the L2-norm of the errors in the velocities and -the pressure. We show that optimal order estimates are -obtained when polynomials of degree k are used for each -component of the velocity and polynomials of degree k-1 for the -pressure, for any k>1. We also consider the case in which -all the unknowns are approximated with polynomials of degree k -and show that, although the orders of convergence remain the same, the -method is more efficient. Numerical experiments verifying these facts -are displayed. - - - - diff --git a/deal.II/doc/publications/2000/gk.bib b/deal.II/doc/publications/2000/gk.bib deleted file mode 100644 index 13ec5aa838..0000000000 --- a/deal.II/doc/publications/2000/gk.bib +++ /dev/null @@ -1,19 +0,0 @@ - - - - - -

A Multilevel Discontinuous Galerkin Method

-J. Gopalakrishnan, - G. Kanschat -

Abstract

- - -A variable V-cycle preconditioner for an interior penalty finite -element discretization for elliptic problems is presented. An analysis -under a mild regularity assumption shows that the preconditioner is -uniform. The interior penalty method is then combined with a -discontinuous Galerkin scheme to arrive at a discretization scheme for -an advection-diffusion problem, for which an error estimate is -proved. A multigrid algorithm for this method -is presented, and numerical experiments indicating its robustness -with respect to diffusion coefficient are reported. - - - - diff --git a/deal.II/doc/publications/2000/hartmann-1.bib b/deal.II/doc/publications/2000/hartmann-1.bib deleted file mode 100644 index 9ddaf11933..0000000000 --- a/deal.II/doc/publications/2000/hartmann-1.bib +++ /dev/null @@ -1,25 +0,0 @@ - - - - - -

Abstract:

- -

- In this thesis, we develop adaptive finite element methods for - parameter estimation problems involving partial differential - equations as constraints. In these so-called Inverse - Problems, the goal is the identification of a distributed - coefficient in a PDE by measurements of the state variable. This has - important applications where material parameters are to be - recovered, but only indirect measurements are possible, such as - identification of the underground structure from seismic - measurements, or in nondestructive material testing. -

- -

- For this kind of problems, we develop adaptive finite element - discretizations based on error estimates, where the estimates are - both for the error in the minimization functional (i.e. of - ``energy-type'') as well as in arbitrary functionals. Furthermore, - methods are developed to handle constraints on the sought - coefficients, based on active set strategies. The methods developed - are numerically tested at a number of large scale inverse problems - realizing some types of inverse problems that actually occur in - applications. -

Goal-Oriented A Posteriori Error Estimation for Compressible Fluid Flows

Abstract:

- -

- We consider so-called `goal-oriented' a posteriori error - estimation for discontinuous Galerkin finite element approximations to - the compressible Euler equations of gas dynamics. By employing a - hyperbolic duality argument, we derive weighted, or Type I, a - posteriori error estimates which bound the error measured in - terms of certain target functionals of real or physical interest. The - practical advantages of this general approach are illustrated by a - series of numerical experiments. -

Goal-Oriented A Posteriori Error Estimation for Multiple Target Functionals

-R. Hartmann and P. Houston - - -

Abstract:

- -

- In many applications the quantities of interest are a series of - target functionals of the solution to the governing system of - partial differential equations rather than the solution itself. For - example, in the field of aerodynamics, examples include the drag and - lift coefficients of an airfoil immersed into a fluid, the pressure - difference between the leading and trailing edges of the airfoil and - point evaluations of the density or pressure on the profile of the - airfoil. While traditionally these quantities are measured in wind - tunnel experiments, nowadays these experiments are increasingly - replaced by numerical simulations aiming to predict these quantities - to a high level of accuracy. -
- In a series of previous articles, we have developed the theory of - goal--oriented a posteriori error estimation for - discontinuous Galerkin methods applied to inviscid compressible - fluid flows. On the basis of Type I a posteriori bounds we - considered the design of adaptive finite element algorithms that are - capable of generating optimal meshes specifically tailored to the - efficient computation of a single target functional of - practical interest. The purpose of the current article is to extend - this earlier work to the case when several target - functionals of the solution need to be simultaneously approximated - to a given level of accuracy. -
