2nd exaFOAM Workshop

We are excited to announce the second workshop on the exaFOAM project, which is aimed at pushing the boundaries of Computational Fluid Dynamics (CFD) technology using OpenFOAM. Our project partners will share their expertise and best practices in sessions that cover the topics HPC Grand Challenge, Code Improvements, Profiling and Applications.

The project involves the development and validation of a range of algorithmic improvements across the entire CFD process chain, including preprocessing, simulation, I/O, and post-processing. The effectiveness of these improvements will be demonstrated through a suite of HPC Grand Challenges and Industrial Application cases, where engineering design through CFD has contributed significantly to industrial competitiveness and sustainability across various sectors such as transportation, power generation, and disaster prevention, among others.

We invite researchers, practitioners, and students from academia, industry and government organizations to attend this workshop to learn more about the exaFOAM project and its innovative approach to CFD. Participants will also have the opportunity to engage in discussions with experts in the field.



March 22th, 2024 – from 9:00 CET to 17:00 CET


The workshop will be held virtually.
