The Open Porous Media (OPM) initiative is a community effort that encourages open innovation and reproducible research for simulation of porous media processes. OPM coordinates collaborative software development, maintains distributes open-source data sets, seeks to ensure these are available under free license in long-term perspective. In this paper, we present Flow, which reservoir simulator developed industrial use, as well some the individual components used make Flow. descriptions apply...
This paper presents the basic concepts and module structure of Distributed Unified Numerics Environment reflects on recent developments general changes that happened since release first Dune version in 2007 main papers describing state Bastian etal. (2008a, 2008b). discussion is accompanied with a description various advanced features, such as coupling domains cut cells, grid modifications adaptation moving domains, high order discretizations node level performance, non-smooth multigrid...
The Dune project has released version 2.4 on September 25, 2015. This paper describes the most significant improvements, interface and other changes for core modules Dune- Common, Dune-Geometry, Dune-Grid, Dune-ISTL, Dune-LocalFunctions.
Electrical impedance tomography (EIT) is a noninvasive imaging modality, where imperceptible currents are applied to the skin and resulting surface voltages measured. It has potential distinguish between ischaemic haemorrhagic stroke with portable inexpensive device. The image reconstruction relies on an accurate forward model of experimental setup. Because relatively small signal in EIT, finite-element modeling requires meshes more than 10 million elements. To study requirements EIT also...
In this paper we present the new DUNE-ALUGrid module. This module contains a major overhaul of sources from ALUGrid library and binding to DUNE software framework. The main improvements concern parallel feature set library. changes include user-defined load balancing, grid construction, an redesign 2d which can now also be used for computations. addition many have been introduced into code increase efficiency decrease memory footprint. original is widely within community due its good...
Abstract The X-ray flux from free-electron lasers and storage rings enables new spatiotemporal opportunities for studying in-situ operando dynamics, even with single pulses. multi-projection imaging is a technique that provides volumetric information using pulses while avoiding the centrifugal forces induced by conventional time-resolved 3D methods like tomography, can acquire movies (4D) at least three orders of magnitude faster than existing techniques. However, reconstructing 4D highly...
Abstract A two-dimensional nonhydrostatic (NH) atmospheric model based on the compressible Euler system has been developed in (x, z) Cartesian domain. The spatial discretization is a nodal discontinuous Galerkin (DG) method with exact integration. orography handled by terrain-following height-based coordinate system. time integration uses horizontally explicit and vertically implicit (HEVI) time-splitting scheme, which introduced to address stringent restriction step size due high aspect...
We present a new scheme, the compact discontinuous Galerkin 2 (CDG2) method, for solving nonlinear convection-diffusion problems together with detailed comparison to other well-accepted DG methods. The CDG2 method is similar CDG that was recently introduced in work of Perraire and Persson elliptic problems. One main feature compactness stencil which includes only neighboring elements, even higher order approximation. Theoretical results showing coercivity stability Poisson heat equation are...
We present and discuss discontinuous Galerkin (DG) schemes for dry moist atmospheric flows in the mesoscale.We derive terrain-following coordinates on sphere strong-conservation form, which makes it possible to perform computation a Cartesian grid yet conserves momentum density an f -plane.A new DG model, i.e.DG-COSMO, is compared operational model COSMO of Deutscher Wetterdienst (DWD).A simplified version suggested implemented DG-COSMO against dynamical core within DUNE framework, uses...
Abstract In this paper, we consider rigorous a posteriori error estimates for convection dominated initial value problems including recent results those with degenerating diffusion. These are important to control the adaptive local mesh refinement numerical computations, in particular simulation of biodegradation process. Several obtained by experiments will be shown.
