This competition aims at promoting the use of ML based surrogate models to solve physical problems, through a task addressing a CFD usecase: Airfoil design.


We are pleased to announce that the we are starting a series of webinars in support to the participants. The #3 webinar will be on "How to contribute by configuring your ML model & How to compute the global evaluation score ? (Starting kit : notebooks 4 & 5)" and will take place Tuesday 12th December (5pm to 6pm CET time) on Teams.
Registered participants have already received the Teams invitation. If you are not yet registered, and wish to join the webinar, please register first on codabench, or get in touch with us via this email or using the discord channel : (opens new window)

# Competition Overview

This competition aims at promoting the use of ML based surrogate models to solve physicalproblems, through a task addressing a recently published dataset called AirfRANS related to airfoil design (CFD simulation). It will address the challenge of improving baseline solutions of the Airfoils design use case by building ML-based surrogate models. The overall aim is to improve tradeoff between accuracy of obtained solutions and related computational cost, while considering Out-of-Distribution (OOD) generalization and respect of some basic physical constraints.

To do so, the competition rely on our recently proposed benchmarking framework called LIPS (“Learning Industrial Physical Systems”). This framework will be used to evaluate candidate solutions provided by participants regarding significant criteria organized into 3 categories namely: ML related criteria, Physical Compliance criteria and OOD generalization criteria. For each submitted solution, a global score will be computed based on aforementioned criterias to rank it.

The help the development of new physics-informed ML models, participants could use the NVIDIA MODULUS Framework (opens new window), and benefit from NVIDIA support through a dedicated webinar at the beginning of the competition.

Participants should train and fine-tune their models on their own computers based on the provided dataset. A cluster of 8 NVIDIA RTX A6000 (opens new window) GPUs will be made available by Exaion (opens new window) for participants who may not have their own GPU resources. For the training phase, Baseline solutions will be made available to help participants.

# Protocol

The competition will be hosted by the Codabench platform (opens new window). Participants will have to:

  1. create an account;

  2. download a starting kit to prepare their submission;

  3. upload on the Codabench platform their trained ML models. Then, the platform will use the LIPS framework to compute scores for the submission. The score will be published on the Codabench competition page and the participant will also have access to an additional page with detailed metrics.

# Who can take part

Anyone interested in solving physical problems using ML technics is encouraged to participate in this competition. It could be a great opportunity to gather people from ML and the Scientific computing communities to leverage synergies between these two domains.

# Competition phases

# This competition will run over 3 phases:

  • Warm-up phase (4 weeks): participants can get familiar with provided material and the competition platform, make their first submissions and provide feedback to organizers. Based on this feedback, organizers can adjust and improve the competition for the next phase.
  • Development phase (9 weeks): participants will develop their solutions and will be able to test their already trained models against a provided validation dataset. They can also have access continuously to the global score corresponding the submitted solution.
  • Final phase (1 week): organizers prepare the final ranking and official results. A dedicated event will be organized to announce the winners.
