LRZ Garching

The focus of this 5-day course is targeted on researchers with good knowledge in the fundamentals 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 packages, i.e. ANSYS CFX and ANSYS Fluent. 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 both CFD solver systems CFX and Fluent. 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 CFD 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 schedulers like Slurm and LoadLeveler, CFD remote visualization and aspects of successful CFD simulation strategies in such an HPC environment. Finally some aspects of workflow automation using Python as scripting language are targeted as well.

What participants will not learn in this course?

  • Advanced aspects of Linux and computer network infrastructure
  • Geometry creation (CAD, SpaceClaim, DM) and meshing
  • Advanced topics of CFD simulation, like e.g. acoustics, Eulerian and Lagrangian multiphase flows, combustion, radiation, FSI etc.
  • Advanced topics of CFD solver customization with User FORTRAN or User Defined Functions (UDF’s) written in C language.
