Call for Papers: Special Issue on Lattice Boltzmann Methods

I’m acting as guest editor for a special issue on LBM in the computation journal. Computation is an open-access journal of computational science and engineering published quarterly online by MDPI. The Special Issue is concerned with recent advances in the Lattice Boltzmann Method (LBM). The LBM has recently matured as a viable alternative to conventional Computational Fluid Dynamics (CFD) approaches that employ Finite Volume, Finite Difference or Finite Element approximations of continuum physics equations, mostly Read more…

HANNOVER MESSE 2015

Meine beiden Vorträge im Rahmen des CAE-Forums auf der HANNOVER MESSE 2015 zu den Themen “Rechnen auf Grafikkarten – die Zukunft im simulationsgestützten Entwurfsprozess?” “Vorstellung der Ergebnisse der Umfrage ‘Computing’ (CPU, GPU, HPC und Cloud)” waren ein voller Erfolg. Der erste Talk befasste sich mit Chancen und Herausforderungen des Einsatzes von Grafikkarten im simulationsgestützten Entwurfsprozess und beinhaltete neben einer kritischen Reflexion der Einsetzbarkeit kommerzieller Softwarelösungen auch die Entwicklungskonzepte und Potentiale unseres hauseigenen Software-Prototypen elbe. Im zweiten Talk ging es Read more…

ONC Tsunami Workshop 2014

In March 2014, 50 years after the 1964 Alaska earthquake and Tsunami, Ocean Networks Canada organized a two-day technical workshop on Tsunami modeling. The workshop covered advanced modeling and prediction technologies for real-time Tsunami forecasting, detection and alerts. In this context, I presented the potential of the elbe solver for efficient and accurate simulations of wave impact and wave-structure interactions in complex three-dimensional topologies, which can be a valuable contribution to Tsunami warning systems in Read more…

Non-uniform grids in elbe

We recently tested and implemented a grid refinement strategy in the LBM solver elbe. First, the concept was tested in the two-dimensional singlephase module elbeSP2D. The velocity field of a 2D Karman Vortex Street at Re 500 is shown below. After a proper validation of the grid coupling, the interpolation routines will be included in all the remaining elbe modules, including those for free surface and multiphase flows.
