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…

On energy conservation laws in the drift-reduced Braginskii model
Sergio García Herreros, Brenno de Lucca, Davide Mancini +5
A revision of the drift-reduced Braginskii model is presented, focusing on its practical implementation in numerical codes, and systematically analyzing the effect of several commo…

Conservative formulation of the drift-reduced fluid plasma model
Brenno De Lucca, Paolo Ricci, Micol Bassanini +2
A conservative formulation of the drift-reduced fluid plasma model is constructed by analytically inverting the implicit relation defining the polarisation velocity as a function o…
