Data Driven Modelling Special Interest Group

Jump to navigation Jump to search


For us, data-driven modeling comprises a variety of different topics, some of which are listed below:

  • machine learning (ML): combining CFD and ML, e.g., using ML models in CFD or deriving ML models from CFD data
  • data science: analyzing CFD data to guide modeling and decision-making
  • data engineering: aggregating, storing, and processing CFD data

The following list briefly summarizes our current objectives:

  • short term objectives
    • reduce the technical barrier to getting started with data-driven modeling in OpenFOAM to enable more people to include data-driven workflows in their applications or research
    • promote data-driven techniques that are already available in OpenFOAM, e.g., dynamic mode decomposition (DMD)
    • promote third-party libraries for data-driven modeling that are based on or built for OpenFOAM
  • long term objectives
    • aid the understanding of when and how to use data-driven modeling in the CFD workflow
    • accelerate developments and applications of data-driven approaches around OpenFOAM
    • establish tested data-driven techniques as a natural element of CFD simulations to improve accuracy and/or speed

Work process

A detailed roadmap and a collection of resources are available on Github. The GitHub repository is also an excellent means to get in touch (e.g., via GitHub issues). Besides the repository, feel free to contact the SIG's chairs, Andre Weiner and Tomislav Marić, or any other member of the SIG.


We aim to have short virtual meetings (max. 1h) every two months and meet in person, if possible, at the OpenFOAM workshop. The bi-monthly meetings update all members about the recent progress and coordinate upcoming efforts. Everybody is welcome to join our meetings. Past and upcoming meetings are listed below:

  • next virtual meeting: Feb 2024
  • Sep. 26 2023, online, slides
  • July 13 2023, in person, 18th OpenFOAM workshop, Genoa
