Immersed and Discontinuous Finite Element Methods
… of the minimal-dissipation local discontinuous Galerkin method for elliptic problems and construct optimal immersed finite element approximations and discontinuous immersed finite element methods for the Stokes interface problem. In the first part we present an error analysis for …

Spacetime Meshing for Discontinuous Galerkin Methods
… solution of nonlinear phenomena using spacetime discontinuous Galerkin finite element methods. Given a triangulated d-dimensional Euclidean space domain M (a simplicial complex) corresponding to time t = 0 and initial conditions of the underlying hyperbolic spacetime PDE, we construct an …

Mathematical Tools for Discontinuous Dynamical Systems
Nonsmooth equations and discontinuous dynamical systems can be used to model systems in a variety of applications, including modeling of certain physical systems and optimization problems. However, theoretical results are somewhat limited for these classes of problems, restricting their use in …

Discontinuous homomorphisms from Banach algebras of operators
… not strongly; this asks for a special type of discontinuous homomorphism from B(X). Using the categorical notion of a pullback we obtain, jointly with N. J. Laustsen [71], new general results about extensions and prove that such a space exists. The same space is used to answer our third …

Discontinuous modelling of strain localisation and failure
… the entire failure process than a continuum or discontinuous model alone. Through numerical examples, it is shown that the inclusion of a displacement discontinuity during the failure process can lead to a different failure mode than for a continuum-only model.

Error Transport Equations for Unsteady Discontinuous Applications
… of this research is demonstrated on unsteady discontinuous problems, such as Sod's problem.

Stiffness and Strength Predictions of Discontinuous Fiber Composites
… will ultimately lead to the certification of discontinuous fiber composites based on analysis and modest experimental verification. A discontinuous fiber composite (DFC) material system called HexMC is considered in this study. A stochastic (Monte Carlo-type) finite-element modeling approach …

Visualization for high-order discontinuous Galerkin CFD results
This thesis demonstrates a technique that reduces the perceived error introduced in the visualization of higher-order DG solutions with traditional tools. Most visualization techniques work by using the solution at the mesh vertices and linearly interpolating to color the interior of the element. …

Towards Coupled Nonhydrostatic-Hydrostatic Hybridizable Discontinuous Galerkin Method
… NHS solver developed using the hybridizable discontinuous Galerkin (HDG) finite element methodology by taking advantage of the local and global HDG solvers for combining HS with NHS solvers. The multi-dynamics is derived, and the first version is implemented in the HDG framework to quantify …

High order hybrid discontinuous Galerkin regional ocean modelling
… new numerical schemes based on the novel hybrid discontinuous Galerkin (HDG) method in combination with projection methods. The new numerical schemes are first derived for the Navier-Stokes equations. To ensure mass conservation, we define numerical fluxes that are consistent with the discrete …

The mRNA Cap and Discontinuous Transcription in Trypansoma brucei
… cap structure may have a functional role in discontinuous mRNA synthesis. These findings will be useful in future in vitro and in vivo studies. In particular, an authentic trypanosome cap may be necessary to obtain an in vitro mini-exon joining reaction.</p>

A Spacetime Discontinuous Galerkin Method for Hyperbolic Conservation Laws
… in the immediate vicinity of shocks and other discontinuous solution features. We address this requirement with a diffusion operator whose intensity is controlled by a shock indicator that measures the relative strength of the high-frequency components of the SDG approximation. Results …
