The focus of this course with its 12 lectures and about 5 practical exercises is targeted on students, PhD's and researchers with good knowledge in the fundamentals of fluid mechanics, numerical methods of fluid mechanics and potentially with some first experience in Computational Fluid Dynamics (CFD). The course will focus on the introduction to the ANSYS Fluid Dynamics software package ANSYS CFX with its components CFX-Pre, CFX Solver Manager and CFD-Post. Further, participants will be familiarized with the main steps of the typical CFD workflow, in particular with CFD preprocessing / CFD setup creation, serial and parallel solver execution and CFD postprocessing in ANSYS CFX. Correctness of boundary conditions and CFD setup specifications, solver convergence control, solver monitoring, customization capabilities of the solvers and the post­pro­cessing as well as recommended CFD best practices are covered.

The course further focusses on the usage of the ANSYS CFX software in a typical Linux cluster environment for massively parallel computations. This includes a basic Linux primer, introduction to LRZ HPC systems and network environment, intro to the use of the SLURM scheduler, CFD remote visualization and aspects of successful CFD simulation strategies in such an HPC environment. Finally some aspects of advanced workflow automation using Python as scripting language in combination with the CCL/CEL scripting language of ANSYS CFX are targeted as well.
