  • Preliminary meeting: Jan 19 2015, 18:00, room 02.07.023
  • Max. number of participants: 19
  • The seminar will be completely in English, so the students also have to give their talks and to write their papers in English.


Lattice Boltzmann methods (LBMs) are used to study flow problems on the statistical scale. Their relatively simple, (mostly) local algorithmics and their meso-scale nature make these methods attractive for both physicists and computer scientists. The latter is particularly true with respect to the field of high performance computing. In this seminar, the basic theory of the Lattice Boltzmann methods is discussed and implementational concepts are presented for single-core and multi-core architectures. Besides, particular aspects such as grid refinement and application of LBMs to more complex systems such as multiphase flows are addressed.

Topic-specific literature will be handed out to the individual participants of the course by the advisors.


For successful completion of the seminar course you have to fulfil the following tasks:

  • solid understanding of your topic (e.g. by implementation of the underlying algorithm)
  • writing of a paper (about 8 pages)
  • presentation (30 min + discussion)
  • participation in the presentations of all other participants
  • deadlines: t.b.a.

The paper template is available here. Usage of Latex is required.
