This work proposes a novel methodology for turbulence modeling in Large Eddy Simulation (LES) based on Graph Neural Networks (GNNs).
The proposed approach embeds the symmetries of the Navier-Stokes equations into the model architecture, resulting in a symmetry-preserving simulation setup.
The GNN models are trained successfully in actual simulations using Reinforcement Learning (RL), ensuring consistency with the underlying LES formulation and discretization.
The GNN model demonstrates the potential for turbulence modeling, particularly in the context of LES and RL.
