A Defect Corrected Finite Element Approach for the Accurate Evaluation of Magnetic Fields on Unstructured Grids
Ulrich Römer, Sebastian Schöps, Herbert De Gersem
In electromagnetic simulations of magnets and machines one is often interested in a highly accurate and local evaluation of the magnetic field uniformity. Based on local post-proce…
A dual consistent finite difference method with narrow stencil second derivative operators
Sofia Eriksson
We study the numerical solutions of time-dependent systems of partial differential equations, focusing on the implementation of boundary conditions. The numerical method considered…
A mixed variational discretization for non-isothermal compressible flow in pipelines
Herbert Egger
We consider the non-isothermal flow of a compressible fluid through pipes. Starting from the full set of Euler equations, we propose a variational characterization of solutions tha…
A robust conservative mixed finite element method for compressible flow on pipe networks
Herbert Egger
We consider the numerical approximation of compressible flow in a pipe network. Appropriate coupling conditions are formulated that allow us to derive a variational characterizatio…
Extrapolation-Based Implicit-Explicit Peer Methods with Optimised Stability Regions
Jens Lang, Willem Hundsdorfer
In this paper we investigate a new class of implicit-explicit (IMEX) two-step methods of Peer type for systems of ordinary differential equations with both non-stiff and stiff part…
Super-convergence and post-processing for mixed finite element approximations of the wave equation
Herbert Egger, Bogdan Radu
We consider the numerical approximation of acoustic wave propagation problems by mixed BDM(k+1)-P(k) finite elements on unstructured meshes. Optimal convergence of the discrete vel…
