The Conference Journées Ondes du Sud-Ouest 2025 is organized at the University of Pau and Pays de l’Adour from March 18th to 20th Conference website: https://joso-2025.github.io/ The Journées Ondes du Sud-Ouest are an opportunity to bring together researchers from south-west France who are contributing to the simulation of wave propagation…
A new preprint is available online:Enriching continuous Lagrange finite element approximation spaces using neural networks Abstract This work concerns the implementation of the hybridizable discontinuous Galerkin (HDG) method to solve the linear anisotropic elastic equation in the frequency domain. First-order formulation with the compliance tensor and Voigt notation are employed…
A Workshop between Inria Makutu and MUMPS group We welcome the Mumps group for a one-day meeting related to the large-scale sparse solver MUMPS and its use in wave modeling and inversion within the team Makutu.
Florian Faucher got awarded the 2024 EAIP Young Scientist Award of the Eurasian Association on Inverse Problems (EAIP) during the 11th International Conference “Inverse Problems: Modeling and Simulation”. https://www.eurasianip.org/eaip-awards/eaip-young-scientist-award.html
Dr Janosch Preuss from University College London is visiting Makutu from May 20th to 25th. He will give the following seminar: A hybridized Nitsche method for acoustic metamaterials abstract: Acoustic metamaterials have some seemingly magical properties. For example, they can be used to render objects invisible to incoming sound waves…
Prof. Maarten V. de Hoop from Rice University is visiting Makutu on March 18th and 19th. He will give the following seminar: Geometry and seismology on gas giants, and inverse problems abstract: It is often useful to treat planets as geometric objects where the geometry is defined so that the…
