Multi-Level GNN Preconditioner for Solving Large Scale Problems

no code implementations13 Feb 2024 Matthieu Nastorg, Jean-Marc Gratien, Thibault Faney, Michele Alessandro Bucci, Guillaume Charpiat, Marc Schoenauer

The proposed GNN-based preconditioner is used to enhance the efficiency of a Krylov method, resulting in a hybrid solver that can converge with any desired level of accuracy.

An Implicit GNN Solver for Poisson-like problems

no code implementations6 Feb 2023 Matthieu Nastorg, Michele Alessandro Bucci, Thibault Faney, Jean-Marc Gratien, Guillaume Charpiat, Marc Schoenauer

This paper presents $\Psi$-GNN, a novel Graph Neural Network (GNN) approach for solving the ubiquitous Poisson PDE problems with mixed boundary conditions.

DS-GPS : A Deep Statistical Graph Poisson Solver (for faster CFD simulations)

no code implementations21 Nov 2022 Matthieu Nastorg, Marc Schoenauer, Guillaume Charpiat, Thibault Faney, Jean-Marc Gratien, Michele-Alessandro Bucci

This paper proposes a novel Machine Learning-based approach to solve a Poisson problem with mixed boundary conditions.

Machine Learning model for gas-liquid interface reconstruction in CFD numerical simulations

no code implementations12 Jul 2022 Tamon Nakano, Alessandro Michele Bucci, Jean-Marc Gratien, Thibault Faney, Guillaume Charpiat

The volume of fluid (VoF) method is widely used in multi-phase flow simulations to track and locate the interface between two immiscible fluids.
