Welcome to the Réseau Numérique en Terre Solide (NuTS), a CNRS thematic network (RT) dedicated to fostering a vibrant community of developers and users of numerical tools for solid Earth sciences. Our mission is to enhance the visibility, efficiency, and knowledge-sharing within this community through a series of conferences and training courses focused on digital science—ranging from data manipulation to high-performance scientific computing.

We are thrilled to announce the third workshop of the NuTS RT, taking place from May 19th to May 22nd in Grenoble. This workshop will focus on data: its management, complex and heavy workflows, storage, analysis, visualization, representation, AI-driven data management, and information extraction. The event is divided into two parts: the first two days will feature scientific talks, while the last two days will offer hands-on practical sessions on two key topics (see the program below).

During the practical sessions, participants will have the opportunity to work with Jupyter Notebooks and the Python programming language, leveraging the state-of-the-art computing resources provided by the MesoNET facility Phileas, hosted by the GLiCID mesocenter in Nantes. The practicals will cover a variety of topics, as outlined in the program below.

We are also organizing a poster session dedicated to scientific projects that involve data management, representation, storage, and related challenges—particularly those still in progress and in need of further discussion. We encourage contributions from students and researchers interested in sharing their ongoing work and ideas with the community.

Join us for this exciting workshop to learn from leading experts, gain hands-on experience in programming related to inverse problems, and connect with fellow researchers in solid Earth sciences. Don’t miss this opportunity to advance your skills and knowledge in numerical and computational science!

The presentations and notebooks will be available here very soon…

If you have any questions or need assistance for late registration, feel free to reach out to us. We look forward to welcoming you to Grenoble!

Practicals

9-11h  Julien Tierny (Sorbonne Université)

Tutorials for re-producing these experiments are available on the TTK website: https://topology-tool-kit.github.io/

In this exercise session, we will experiment with multi-scale filament extraction within geoscience data, based on Topological Data Analysis. We will review how to open a dataset, compute its persistence diagram, simplify the data based on its most persistent features and extract the corresponding filament structure with the Morse-Smale complex.

We will both experiment with this pipeline in an interactive exploration context with ParaView's user interface, as well as in a batch mode with ParaView's Python API.

11h-12h Léonard Seydoux (IPGP).  "Programmer avec l’IA générative"
