A Physics-Informed Neural Network for Solving the Quasi-static Magnetohydrodynamic Equations

Jonathan S. Arnaud, Christopher J. McDevitt, Golo Wimmer +1

A physics-informed neural network (PINN) is developed, for the first time, to learn the time-dependent quasi-static magnetohydrodynamic (MHD) equations in axisymmetric tokamak geom…
