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…

Can the perfect Swiss alphorn be designed? A combination of reduced basis method and machine learning for shape optimization
Fabio Marcinnò, Clément Froidevaux, Leonardo Bocchieri +3
In this work, we investigate the shape optimization of a Swiss alphorn to achieve resonance frequencies as close as possible to prescribed target notes. We construct an accurate ge…
