OpenTELEMAC and HPC: high-performance modeling of climate-related hydraulic hazards
By Fabien Leray, President, Simvia groupe EDF

Faced with the challenges of climate change, hydraulic modeling requires precision and speed. OpenTELEMAC software, combined with high-performance computing (HPC), enables detailed simulations of large-scale coastal and river flows. This presentation shows how this synergy improves the identification of vulnerable areas and facilitates the proactive design of effective adaptation measures.

Biography: Fabien Leray is Chairman and founder of Simvia, an EDF subsidiary dedicated to the distribution of open source digital simulation solutions for industrial engineering. An engineer by training, he began his career in nuclear operational safety before joining EDF R&D, where he managed digital transformation projects for the nuclear fleet. Today, he is working to democratise access to advanced simulation tools such as Code_Saturne and Code_Aster, by promoting collaborative innovation and the opening up of technologies within the scientific and industrial community.
