A fast parallel solver for the forward problem in electrical impedance tomography
Jehl, Markus; Dedner, Andreas; Betcke, Timo; Aristovich, Kirill; Klöfkorn, Robert; Holder, David (Journal article; Peer reviewed, 2015-01)Electrical impedance tomography (EIT) is a noninvasive imaging modality, where imperceptible currents are applied to the skin and the resulting surface voltages are measured. It has the potential to distinguish between ... -
Asynchronous communication in spectral-element and discontinuous Galerkin methods for atmospheric dynamics – a case study using the High-Order Methods Modeling Environment (HOMME-homme_dg_branch)
Jamroz, Benjamin F.; Klöfkorn, Robert (Journal article; Peer reviewed, 2016-08)The scalability of computational applications on current and next-generation supercomputers is increasingly limited by the cost of inter-process communication. We implement non-blocking asynchronous communication in the ... -
On discontinuous Galerkin approach for atmospheric flow in the mesoscale with and without moisture
Schuster, Dieter; Brdar, Slavko; Baldauf, Michael; Dedner, Andreas; Klöfkorn, Robert; Kröner, Dietmar (Journal article; Peer reviewed, 2014-06)We present and discuss discontinuous Galerkin (DG) schemes for dry and moist atmospheric flows in the mesoscale. We derive terrain-following coordinates on the sphere in strong-conservation form, which makes it possible ... -
The DUNE-ALUGRID Module
Alkämper, Martin; Dedner, Andreas; Klöfkorn, Robert; Nolte, Martin (Journal article; Peer reviewed, 2016-01)In this paper we present the new Dune-ALUGrid module. This module contains a major overhaul of the sources from the ALUGrid library and the bindings to the Dune software framework. The main improvements concern the parallel ...
