A stencil scaling approach for accelerating matrix-free finite element implementations
Simon Bauer, Daniel Drzisga, Marcus Mohr +3
We present a novel approach to fast on-the-fly low order finite element assembly for scalar elliptic partial differential equations of Darcy type with variable coefficients optimiz…
Highly sparse surface couplings for subdomain-wise isoviscous Stokes finite element discretizations
Markus Huber, Ulrich Rüde, Christian Waluga +1
The Stokes system with constant viscosity can be cast into different formulations by exploiting the incompressibility constraint. For instance the strain in the weak formulation ca…
Solution Techniques for the Stokes System: A priori and a posteriori modifications, resilient algorithms
Markus Huber, Lorenz John, Petra Pustejovska +3
This article proposes modifications to standard low order finite element approximations of the Stokes system with the goal of improving both the approximation quality and the paral…
Pore-scale lattice Boltzmann simulation of laminar and turbulent flow through a sphere pack
Ehsan Fattahia, Christian Waluga, Barbara Wohlmuth +3
The lattice Boltzmann method can be used to simulate flow through porous media with full geometrical resolution. With such a direct numerical simulation, it becomes possible to stu…
Large scale lattice Boltzmann simulation for the coupling of free and porous media flow
Ehsan Fattahi, Christian Waluga, Barbara Wohlmuth +1
In this work, we investigate the interaction of free and porous media flow by large scale lattice Boltzmann simulations. We study the transport phenomena at the porous interface on…
