EuroCC@Greece and the National Technical University of Athens announced the 10th Course of the HPC Training Series with subject \u201cIntroduction to Computational Fluid Dynamics and OpenFOAM, using High Performance Computing\u201d, that took place online on February 17th, 2025.<\/p>\n
Presentation languages<\/strong>: Greek & English<\/p>\n Audience<\/strong>: Suitable for students, researchers, and engineers working in the field of Computational Fluid Dynamics (CFD), who are interested in working in an HPC environment.<\/p>\n Location<\/strong>: Online via Zoom<\/p>\n Description<\/strong>: The course included an introduction to High-Performance Computing (HPC) and Computational Fluid Dynamics (CFD) using OpenFOAM, with a demonstration of the SLURM job submission system. The session began with setting up and troubleshooting a virtual HPC environment, which attendees installed on their own machines to simulate an HPC experience. The schedule covered fundamental concepts of CFD, such as the notions of a mesh, turbulence modeling, solution algorithms and discretization schemes and introduces OpenFOAM\u2019s features and history. Attendees submitted and managed CFD jobs in a simulated HPC environment. The course concluded with examples of high fidelity simulations from various engineering domains, from Politecnico di Milano.<\/p>\n Objectives<\/strong>: The objective of the training was to introduce newcomers to basic concepts related to CFD and to make them familiar with the open-source CFD toolbox OpenFOAM. Additionally, at the end of the training, the attendees should have had understood how a job submission tool, like SLURM, can be used to submit and track jobs in an HPC environment. A final objective was to inform the attendees about the CPU cost of demanding CFD cases and how HPC can help them tackle such problems at reasonable turnaround times.<\/p>\n Prerequisites<\/strong>: Familiarization with a Linux-like Command Line Interface (CLI) was necessary to navigate around the example cases that will be provided and to make small modifications to them. A CLI-based editor (vi, emacs, nano, etc) was also useful to manipulate the provided cases but was not strictly necessary. The attendees that wanted to follow the hands-on part of the training had to download a Docker image\u00a0 that included OpenFOAM and a virtual HPC environment, containing SLURM. Finally, basic understanding of fluid mechanics, linear algebra and CFD were also useful background knowledge for following the training.<\/p>\n The course\u2019s agenda and presentation material can be found here<\/a>.<\/p>\n
