The event is intended to be an inaugural workshop to mark the official launch of the newly formed ERCOFTAC Special Interest Group - SIG55 on Advanced Numerical Methods for Scale-Resolving Simulations. The workshop aims to bring together a diverse group of researchers and practitioners, ranging from established experts to early-career scientists and PhD students, as well as industrial partners, to define a shared vision and lay the groundwork for a next-generation roadmap in computational fluid dynamics (CFD) research and development. With a growing need for robust, accurate and efficient CFD tools capable of tackling multi-scale and multi-physics flow problems, the workshop will provide a platform to identify key challenges and foster interdisciplinary exchange toward innovative numerical strategies, open-source software frameworks, and community-driven benchmark definitions in the context of scale-resolving simulation.

 

Objectives:

The primary goals of the workshop are to:

  • Establish a core community and foster interdisciplinary dialogue among researchers working on scale-resolving CFD, numerical analysis, and physical modeling;
  • Discuss strategies for reconciling numerical robustness, physical fidelity, and computational efficiency in direct and large-eddy simulations;
  • Attract and involve young researchers by providing a platform for discussion, collaboration, and visibility;
  • Initiate collective efforts towards the definition of new relevant benchmark cases for advanced numerical methods and complex flow configurations;
  • Promote open-source software development and coordinate the implementation of structure-preserving schemes in existing platforms;
  • Attract practitioners (industrial partners) that will ultimately apply the methods and can provide input to their development.

 

Format and Activities:

The 2-day workshop will be structured around:

  • Keynote lectures from leading researchers on structure-preserving discretizations, advanced closure modeling, and software implementations;
  • Contributed posters from early-career researchers;
  • Roundtable discussions on the future directions, benchmark case definition and open-source CFD implementations;
  • A roundtable discussion on collaborative projects and SIG growth strategies.

 

Impact and Expected Outcomes:

This first SIG event will serve as a catalyst to consolidate the community, assess the current landscape of CFD, lay the groundwork for future collaborative efforts and align research directions. It will also help create a common roadmap for numerical benchmarking and software integration.
