GTC Europe 2016


The elbe team was part of the first European GPU Technology Conference that took place on September 28-29 in Amsterdam, Netherlands. More than 1700 attendees were on site to learn about deep learning, artificial intelligence and high performance computing on graphics processing units. I was one of the featured speakers in the HPC track with my talk about “Number-Crunching on the Desktop for Simulation-Based Design – the Future of Computational Fluid Dynamics”. The talk was recorded and will be available online soon – check for further details.

SMM 2016

Busy 2016! After having successfully organized ICMMES-2016, we’re now contributing to this years’ SMM exhibition. SMM is the leading international maritime trade fair and will take place from Sept 6 thru Sept 9 2016, in Hamburg, Germany. Together with other research teams from our host institute, the Institute for Fluid Dynamics and Ship Theory (FDS), we’re going to present recent research results and maritime applications of the elbe code. Feel free to stop by at our joint stand (hall b7, stand 117) for further information or check the official SMM web page.


icmmes_bannerWe’ve been rather busy lately, as we’re currently organizing the 13th International Conference for Mesoscopic Methods in Engineering and Science (ICMMES 2016). Further details can be found on the official conference web page,, and on Facebook,

Following the tradition established by previous ICMMES conferences, short courses will be offered on Monday, July 18, 2016. From Tuesday, July 19, till Friday, July 22, there will be 4 days of technical presentations.

Hamburger KOMPASS 2016

I’m very proud to announce that we received the “Hamburger KOMPASS 2016” award for our innovative and groundbreaking maritime research at TUHH. The price was awarded on April 7th 2016 during the Hamburger Hafenempfang. We’ll publish more details including more/better pictures from the award ceremony ASAP.

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 Navier-Stokes (NS). Whilst modeling essentially similar physics as classical continuum mechanics NS procedures, LBM features a number of advantages, particularly concerning data locality and parallel computing, but also in terms of stability and dispersion properties. As the method originates from the Boltzmann equation (being a superset of NS), multi-scale modeling (even up to specific kinetic turbulence models) is possible. The SI aims at highlighting the current state-of-the-art in the field of LBM and future research directions. Both submissions with an academic background as well as more application-oriented contributions are welcome.

For further details and submission of papers, see the official journal webpage.


Marine 2015

The elbe team will present several elbe-related results at the sixth Conference on Computational Methods in Marine Engineering (Marine 2015) in Rome. Both talks are scheduled in the CFD II session on Wednesday morning:

Wednesday, June 17th
09:30 – 10:40
Numerical Methods in CFD II

GPU-Accelerated Large-Eddy Simulation of Ship-Ice Interactions
D. Mierke, C.F. Janßen and T. Rung

A next-generation CFD tool for large-eddy simulations on the Desktop
C.F. Janßen, N. Koliha and T. Rung

Moreover, there will be three other talks from our FDS team: Prof. Rung will kick off the conference with a keynote on “Predictive Prospects of Marine-Engineering Simulations” (Monday, 09:00 – 09:45). Wibke Wriggers will talk about “Numerical Modelling of Granular Cargo on Bulk Carriers in Seaway” (Tuesday, 09:30 – 10:40) and Svenja Völkner will present “An overset-grid three-phase flow model for offshore operations” (Wednesday, 11:10 – 13:00).



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 um die Ergebnisse einer Meinungsumfrage, die u.a. den im Simulationsbereich vorhandenen Bedarf an High Performance Computing adressierte. Im Speziellen wurden mögliche Konzepte zur Deckung dieses Bedarf diskutiert und zwei Lösungen, Cloud Computing oder GPU-gestützte Beschleunigung, gegenübergestellt.
