SIG55 Workshop
Advanced Numerical Methods for Scale-Resolving Simulations
22nd - 23rd January 2026
CWI, Amsterdam, The Netherlands
The program is available on the congress website: TBC
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;
- Invited and contributed talks from senior researchers;
- Contributed presentations and posters from early-career researchers;
- Open discussion sessions on benchmark case definition and software/tool interoperability;
- A roundtable discussion on future directions, 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.
