Lisbon, Portugal – At the prestigious 9th European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS Congress 2024), Dr. Christophe Coreixas, from the Institute of Advanced Study (IAS), delivered a groundbreaking presentation on advanced computational fluid dynamics. In addition to his own research, he contributed to five other innovative research projects presented by his collaborators from the Computer Science and Earth Science departments at the University of Geneva (UNIGE), and the Geothermal Energy & Geofluids group at ETH Zurich (ETHZ) in Switzerland. These projects showcased a broad spectrum of cutting-edge advancements, with applications ranging from aerospace and geothermal energy to volcanic eruption predictions.

Cutting-Edge Research on Mesh Refinement on GPU for Lattice Boltzmann Methods

Dr. Christophe Coreixas presented the latest findings on mesh refinement on Graphical Processing Units (GPUs) within the Lattice Boltzmann (LB) framework. The research, entitled "Mesh refinement on GPU for lattice Boltzmann methods: Application to subsonic and supersonic flow simulations", focuses on the development of C++ based GPU-accelerated LB solvers that operate efficiently on non-uniform grids regardless of the velocity discretization. The long-term goal of this research is to provide simulation tools to academic and industrial groups to better predict realistic, complex physical phenomena while minimizing costs, energy consumption, and corresponding CO2 emissions.

Collaborative projects dedicated to aerospace, geothermal and volcanic eruption predictions

Dr. Coreixas also contributed to five other research projects in collaboration with the Computer Science and Earth Science departments of UNIGE, as well as the Geothermal Energy & Geofluids group at ETH Zurich (ETHZ):

1. "Performance Optimality in GPU-based, Mesh-Refined LBM Codes" by Latt and Coreixas, offering insights into efficient Octree-based LBM codes for industrial applications.

2. "Exponential Distribution Functions for Positivity-Preserving Lattice Boltzmann Schemes: Validations in 3D" by Thyagarajan et al., highlighting collaborative work between IAS and UNIGE on supersonic flows relevant to the aerospace industry.

3. "A TRT Lattice-Boltzmann Solver for Pore-Scale Conjugate Heat Transfer in Porous Media" by Schwendener et al., focusing on geothermal applications explored through collaborative efforts of IAS, UNIGE, and ETHZ.

4. "Modelling of Volcanic Plumes and Clouds: Implementation of Wind-Caused Bending Effects and Coarse Particles in a Multi-GPU Accelerated LBM-WENO Code" by Simionato et al., presenting results from collaborative work between IAS and UNIGE on predicting ash sedimentation encountered during volcanic eruptions.

5. "Development of a Multi-GPU Accelerated Code to Model the Complex Dynamics of Volcanic Plumes Using the Lattice Boltzmann Method" by Lemus et al., showcasing further insights into volcanic eruption dynamics through joint efforts of IAS and UNIGE.
