Computational Fluid Dynamics and Simulation Lab

This interdisciplinary practical course focuses on applications of mathematics for simulations on high performance computers, e.g., for computational fluid dynamics. Within this context, the interlocking concepts of

• mathematical modeling,
• numerical simulation (with lattice Boltzmann methods),
• high performance computing and
• presentation and evaluation of results

are taught with the help of examples.

Under guidance, a fluid dynamics problem is formulated, simulated and hence evaluated with the help of the computational results. Therefor, the C++ software library OpenLB is provided and its usage on high performance computers (such as HoreKa) is enabled.

The projects are carried out in small groups that are supervised by doctoral students. At the end of the project phase, a written report has to be submitted. Each group gives a short presentation to highlight specific results obtained during the course. Own project topics suggested by the participating students are welcome.

This course is funded by the Federal Ministry of Education and Research (BMBF) and the Baden-Württemberg Ministry of Science as part of the Excellence Strategy of the German Federal and State Governments.
