We present an algorithmic framework for matrix-free evaluation of discontinuous Galerkin
finite element operators. It relies on fast quadrature with sum factorization on quadrilateral …

Abstract In shock-induced Richtmyer–Meshkov instability, the polygonal bubbles, including
the rectangular interface can offer favorable circumstances for shock refraction research …

We present an implicit Large Eddy Simulation (iLES) h/p high order (≥ 2) unstructured
Discontinuous Galerkin–Fourier solver with sliding meshes. The solver extends the laminar …

We present fully resolved computations of flow over periodic hills at the hill-Reynolds
numbers Re H= 5, 600 Re_H=5,600 and Re H= 10, 595 Re_H=10,595 with the highest …

This text presents contributions to efficient high-order finite element solvers in the context of
the project ExaDG, part of the DFG priority program 1648 Software for Exascale Computing …

A scheme for the solution of fluid–structure interaction (FSI) problems with weakly
compressible flows is proposed in this work. A novel hybridizable discontinuous Galerkin …

SUMMARY We introduce SPECFEM2D-DG, an open-source, time-domain, hybrid Galerkin
software modelling the propagation of seismic and acoustic waves in coupled solid–fluid …

The present work develops hybrid multigrid methods for high-order discontinuous Galerkin
discretizations of elliptic problems, which are, for example, a key ingredient of …

This paper investigates the dynamics of Richtmyer–Meshkov instability (RMI) in shocked
backward-triangular bubbles through numerical simulations. Two distinct gases, He and SF …

Two-phase flow with viscosity contrast at the pore scale is modeled by a time-dependent
Cahn–Hilliard–Navier–Stokes model and belongs to the class of diffuse interface method …
