Title: Modeling fully 3D MHD Equilibria on GPU with MRX
Description
We present the MHD equilibrium solver MRX, based on the magnetic relaxation approach. We describe the mathematical theory behind this method and discuss what can be transferred to the fully discrete setting of a relaxation code. An inexact Newton method enables the computation of high-resolution finite-beta equilibria with islands and chaos in minutes on a single GPU. Numerical examples are shown for a finite-beta NCSX configuration.
Short bio: Tobias Blickhan is a Faculty Fellow at the Courant Institute of Mathematical Sciences, New York University. He received his PhD in Mathematics from TU Munich in 2025, working in the Numerical Methods for Plasma Physics Division at the Max Planck Institute for Plasma Physics with Eric Sonnendrücker and Michael Kraus.
