Success Story: Multi-scale and multiphysics simulation of a dam
NCC presenting the success story
The French NCC: CC-FR, dedicated to HPC, HPDA and AI technologies, brings together the community of technology providers and users. CC-FR federates the HPC, HPDA and AI ecosystem and supports SMEs on the use of intensive computing, high-performance data analysis and artificial intelligence.
Industrial Organisations Involved:
CC-FR, set up within the framework of EuroHPC, is managed by the European Pole of Competence in high performance digital simulation Teratec, in association with the European Center for Advanced Research and Training in Scientific Computing Cerfacs and with the participation of the Big National Equipment Intensive Computing Genci.

Name: CEVAA ; Website : https://cevaa.com
CEVAA specialized in acoustics and mechanics, offers its test equipment and its expertise to Industry. Numerical simulation by finite elements is a major tool, with various specialized software and a dedicated team of engineers.
In 2021, CEVAA was asked to study the mechanical strength of a dam. With scales ranging from centimeters to several tens of meters, taking into account loads multiphysics (temperature, pressure, forces), the internal software and computing resources of CEVAA were insufficient to conduct the study.
In the case of the dam illustrated above, it was the need for memory that prevented the study from being carried out on our servers. Moreover, the use of Myria has made it possible to carry out several simulations simultaneously, and to obtain a delivery time in agreement with the customer need.
Finally, the remote viewing service makes it possible to perform pre and post-processing operations very smoothly on the calculator, without having to move the data.
CEVAA requested The French NCC support to use HPC Computing resources as well as the latest sequential and parallel versions of Code_Aster for the realization of a multi–scale simulation and multiphysics simulation of a dam. The study was carried out on the CRIANN Myria calculator with Code_Aster for calculations and SalomeMeca for mesh and post-processing.
The project received advanced support from the CRIANN, with the installation of the latest versions Code_Aster sequential and parallel (versions 13 and 14), then help in the creation of the scripts to launch calculations. Several dozen calculations were launched on 8 CPU cores and 120 GB of memory.
The Tailored program of CC-FR enable large client projects to be carried out with a significant productivity gain .
