Description

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.

Requirements

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.
