A fast parallel solver for the forward problem in electrical impedance tomography
(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 ... -
A theoretical look at ensemble-based optimization in reservoir management
(Journal article; Peer reviewed, 2016-05)Ensemble-based optimization has recently received great attention as a potentially powerful technique for life-cycle production optimization, which is a crucial element of reservoir management. Recent publications have ... -
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)
(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 ... -
Footprints of spontaneous fluid redistribution on capillary pressure in porous rock
(Journal article; Peer reviewed, 2017-05)Pore-scale imaging of two-phase flow in porous media shows that pore filling occurs as cooperative events with accompanying spontaneous fluid redistribution in other parts of the pore space. We present a level set method ... -
Incorporating electrostatic effects into the effective stress relation — Insights from chalk experiments
(Journal article; Peer reviewed, 2018-01)Which forces are responsible for holding highly porous chalks together? We use the effective stress to quantify the electrostatic effects around particle contacts originating from the adsorption of ions onto charged mineral ... -
On discontinuous Galerkin approach for atmospheric flow in the mesoscale with and without moisture
(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
(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 ...
