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…

Constructing nested coordinates inside strongly shaped toroids using an action principle
Zeno Tecchiolli, Stuart Hudson, Joaquim Loizu +3
A new approach for constructing polar-like boundary-conforming coordinates inside a toroid with strongly shaped cross-sections is presented. A coordinate mapping is obtained throug…
