PLENARY TALK - Sigal Gottlieb

 

 

Strong Stability Preserving Time Discretization

 

 

Strong stability preserving (SSP) high order time discretizations were developed to ensure nonlinear stability properties necessary in the numerical solution of hyperbolic partial differential equations with discontinuous solutions. SSP methods preserve the strong stability properties, in any norm, seminorm or convex functional, of the spatial discretization coupled with first order Euler time stepping. In this talk I will discuss development of SSP methods and review the SSP properties of explicit and implicit SSP RungeKutta, multistep, and multistep multistage methods, for both linear and nonlinear problems.

PLENARY TALK - Tom Hagstrom

Robust High-Order Methods for Waves

The defining feature of waves is their ability to propagate long distances relative to their wavelength. As more powerful computing platforms become available, it is natural to address evermore challenging problems involving complex geometrical features in computational domains encompassing many wavelengths. This is precisely the setting where the low dissipation/dispersion errors of high-order methods can make their mark. For example, to propagate a wave one hundred wavelengths with an error of 10% a 10th order discretization requires a factor of more than30 fewer points-per-wavelength than a 2nd order scheme, and thus is more than one thousand times more efficient in 3 + 1-dimensions. The goal of our work is to develop robustly stable methods capable of approaching the efficiency of simple difference methods on uniform grids while still maintaining accuracy in the presence of complex geometry. To do so we advocate: i. Unstructured grids near geometrical features using upwind discontinuous Galerkin discretizations in space; ii. More efficient structured grid methods in the bulk of the domain based either on dissipative Hermite or Lagrange interpolation; iii. Coupling structured and unstructured grids relying on the inherent dissipativity of the schemes to guarantee stability; iv. Coupling with local radiation boundary conditions of certifiable accuracy to limit the computational domain.

PLENARY TALK - Thomas Wihler

On Some Recent Progress in HP-Discontinuous Galerkin Methods

 

In this talk we will focus on two different aspects of hp-discontinuous Galerkin (dG) discretizations.
 
In the first part of the presentation, an hp-dG time stepping scheme for first-order systems (in time) will be considered. We will address the existence of discrete solutions for possibly nonlinear problems, and we will look at the application of the method to linear parabolic PDE together with the derivation of some hp-type a posteriori error bounds.  

The second part of the talk will deal with hp-dG spatial discretizations of linear elliptic problems (with possibly mixed boundary conditions), with a particular emphasis on achieving exponential convergence rates.

Nonstandard Finite Element Methods for Higher Order Problems

 

Standard h-version finite element methods for fourth order elliptic problems require the construction of complicated C1 finite element spaces. In this talk we will present two nonstandard finite element methods that can circumvent this difficulty. The first one is a discontinuous Galerkin method that uses standard finite element spaces for second order problems. The second method is a generalized finite element method that is based on a C1 partition of unity. Extensions of these methods to higher order problems will also be discussed.

PLENARY TALK - Martin Costabel

Computing the Inf-Sup Constant of the Divergence

The inf-sup constant of the divergence, also known as LBB constant, is an important characteristic of a domain. It is explicitly known only for a few domains, and whereas in some situations there exist estimates, little is known about how to approximate it numerically. In the talk, we will explain why this is a difficult problem. Three main difficulties conspire here, from finite element analysis, from functional analysis, and from corner singularities.

Because of its relation with stability and error estimates for the Stokes system, estimates of the discrete LBB constant for various h version and hp version finite element schemes have been studied since a long time in computational fluid dynamics. Such estimates typically give lower bounds and do not prove convergence, but they show the importance of the local structure of the finite element space.

Secondly, the problem is equivalent to finding the minimum of the Cosserat spectrum, and this is an eigenvalue problem with a non-trivial essential spectrum, ruling out the usual techniques for analyzing eigenvalue approximation. Finally, the Cosserat eigenfunctions have very strong corner singularities that depend on the eigenvalue and do not leave any regularity above the energy space as one approaches the essential spectrum.

EXPLOITING SUPERCONVERGENCE THROUGH SMOOTHNESS-INCREASING ACCURACY-CONSERVING (SIAC) FILTERING

 

8:00

 

 

There has been much work in the area of superconvergent error analysis for finite element and discontinuous Galerkin (DG) methods. The property of superconvergence leads to the question of how to exploit this information in a useful manner, mainly through superconvergence extraction. There are many methods used for superconvergence extraction such as projection, interpolation, patch recovery and B-spline convolution filters. This last method falls under the class of Smoothness-Increasing Accuracy-Conserving (SIAC) filters. This method is designed to take advantage of the superconvergence property in finite element and discontinuous Galerkin methods. It has the advantage of improving both smoothness and accuracy of the approximation. Specifically, for linear hyperbolic equations it can improve the order of accuracy of a DG approximation from k+1 to 2k+1, where k is the highest degree polynomial used in the approximation. In this talk, we discuss the importance of overcoming the mathematical barriers in making superconvergence extraction techniques useful for applications, specifically focusing on SIAC filtering for discontinuous Galerkin approximations.
