AB - <p style="text-align: justify;">Lattice-Boltzmann (LB) simulations are a common tool to numerically
estimate the permeability of porous media. For valuable results, the
porous structure has to be well resolved resulting in a large
computational effort as well as high memory demands. In order to estimate
the permeability of realistic samples, it is of importance to not only
implement very efficient codes, but also to choose the most appropriate simulation setup to achieve accurate results. With the focus on accuracy
and computational effort, we present a comparison between different
methods to apply an effective pressure gradient, efficient boundary
conditions, as well as two LB implementations based on pore-matrix and
pore-list data structures.</p>
