The ITFD has a powerful computing cluster with more than 1500 CPU cores for demanding calculations and the pre- and post-processing of large-eddy simulations (LES) and direct numerical simulations (DNS). The latest generation of AMD Epyc processors is used, which are connected to a cluster network via InfiniBand. For direct numerical simulations of turbulent flows, the research group uses the high-performance computers of the Steinbuch Center for Computing (SCC).
Student workstations with workstations are available in the institute's CFD laboratory for project, R&D and final theses. In addition, students have exclusive access to a computing cluster with several hundred computing cores.
In addition to the use of open-source and commercial standard calculation programs, various solvers are developed in-house at the institute for special purposes. The modular software package BLPro, programmed in Python, is suitable for calculating boundary layer flows with and without heat transfer very efficiently. In particular for the simulation of transitional boundary layer flows, which change from laminar to turbulent state, a large number of models are available, which are constantly being expanded to include the latest findings from current research. Further focal points are turbulence modeling and models that take the surface structure into account.
