Technical/scientific Challenge:
How to succeed in opening swimming sites in Marne after the Paris 2024 Olympic Games? The Public authorities need to obtain a fine modeling of dispersion bacteriological strains since their point emission. To support the management plans put in place by public authorities in these highly urbanized areas, Prolog engineering has developed a model coupling hydrodynamics and water quality on the Criann supercomputer.
Solution:
PROLOG INGÉNIERIE group, specialized in the field of water and environment was supported by CC-FR to deploy a code coupling hydrodynamics and water quality on the CRIANN Supercomputer to obtain a fine representation of the dispersion of pollution at a bathing area in 3 steps:
Step 1: 2D modeling by the Telemac-Mascaret system representing the conditions hydrodynamics of a 40 km long section of the Marne
Step 2: Prioritization of pollution sources due to permanent or accidental wastewater discharges and rainwater discharges
Step 3: Focus on a potential bathing site. 3D modeling for a fine representation of local dispersion of pollution
Proof of concept that were achieved:
3D hydrodynamic simulation of a section of the river Marne with consideration of pollution sources
Deployment 3D hydrodynamic simulation on HPC architecture
Getting started with the HPC environment
Business impact:
Thanks to CC-FR and CRIANN with a high-level expertise in intensive computing, PROLOG INGÉNIERIE group has been able to significantly increase their expertise to deploy 3D hydrodynamic simulation on HPC architecture. Individual and personalized support has also enabled the company quickly become autonomous in the use of supercomputer and to enable large client to be carried out with a significant productivity gain.
Benefits:
Speed of calculation time
Fine representation of pollution dispersion at bathing area level
More than 120,000 CPU hours was needed
