Title: Improving ideal MHD equilibrium accuracy with physics-informed neural networks
Abstract:
arXiv:2507.03119v5 Announce Type: replace-cross Abstract: We present a novel approach to compute three-dimensional Magnetohydrodynamic equilibria by parametrizing Fourier modes with artificial neural networks and compare it to equilibria computed by conventional solvers. The full nonlinear global force residual across the volume in real space is then minimized with first order optimizers. Already,we observe competitive computational cost to arrive at the same minimum residuals computed by existi
