Implicit-Explicit time integration scheme with Physics-based preconditioning for two-fluid tokamak boundary simulations

Micol Bassanini, Simone Deparis, Paolo Ricci +4

In this work, a globally stiffly accurate Implicit-Explicit (IMEX) Runge-Kutta scheme is developed and implemented in the GBS code [Ricci et al., Plasma Phys. Control. Fusion, 2012…
