Global fluid simulation of plasma turbulence in stellarators with the GBS code
The implementation of three-dimensional magnetic fields, such as the ones of stellarators, in the GBS code (Ricci et al 2012 Plasma Phys.Control.Fusion 54 124047; Giacomin et al 2022 J.Comput.Phys.464 111294) is presented, and simulation results are discussed.The geometrical operators appearing in the drif-reduced Braginskii equations evolved by GB
