A propos du centre ou de la direction fonctionnelle
The Inria Saclay-Île-de-France Research Centre was established in 2008. It has developed as part of the Saclay site in partnership with Paris-Saclay University and with the Institut Polytechnique de Paris since 2021.
The centre has 39 project teams , 27 of which operate jointly with Paris-Saclay University and the Institut Polytechnique de Paris. Its activities occupy over 600 scientists and research and innovation support staff, including 54 different nationalities.
Contexte et atouts du poste
The TAU/A&O team is an Inria joint team with LISN (Laboratoire Interdisciplinaire des Sciences du Numérique), working on Machine Learning and data-based modeling. ML for Numerical Simulation is one of the pillars of TAU research program. In the frame of this project, the team will collaborate with Lionel Mathelin (Dataflot team at LISN) and Alexandre Allauzen (ESPCI). The former will provide his expertise on CFD numerical simulations, while the latter will share his expertise in developing large-scale transformers in the context of natural language applications. Collaboration with the DataMove Inria team is also envisioned, to help tackling the HPC challenges related to data generation and model training.
Mission confiée
Data-driven ML methods have shown potential in reducing the computational costs of numerical simulations, but they often struggle with scalability and versatility. This project aims to develop a Foundational Large Physics Model for fluid simulations. This large model, based on the Transformer architecture, will be pre-trained to solve 3D simulations across various geometries and flow conditions, requiring only light fine-tuning to optimally adapt it to specific problems. Former members of the TAU team have conducted promising proof-of-concept experiments on challenging CFD datasets, but many challenges remain. We are seeking a highly motivated post-doctoral researcher to manage the operational aspects of the project, which includes:
-
Familiarizing with existing solutions developed by the TAU team and studying state-of-the-art approaches that leverage large models for science.
-
Managing the data generation process, including creating comprehensive training datasets from diverse CFD sources and augmenting these datasets with high-fidelity numerical simulations.
- Designing an efficient training strategy, potentially leveraging pre-training approaches from other large models.
-
Evaluating the model's generalization capabilities when fine-tuned for several specific tasks, and its performance compared to other existing Machine Learning methods for solving partial differential equations.
