Acceleration of an Algebraic Multigrid Pressure Solver Using Graph Neural Networks

arXiv·low signal

Uses GNNs to accelerate the algebraic-multigrid solve of the pressure-Poisson equation, the main computational bottleneck in incompressible CFD simulations. A scientific-computing efficiency result with limited transfer to general AI/ML practice. By Eric Chillón, Artur K. Lidtke, Nguyen Anh Khoa Doan et al. (physics.comp-ph/cs.LG/physics.flu-dyn).
