In this work, we compare gyrokinetic simulations in stellarators using different computational domains, namely, flux tube (FT), full-flux-surface (FFS), and radially global (RG) domains. Two problems are studied: the linear relaxation of zonal flows (ZFs) and the linear stability of ion temperature gradient (ITG) modes. Simulations are carried out with the codes EUTERPE, GENE, GENE-3D, and stella in magnetic configurations of LHD and W7-X using adiabatic electrons. The ZF relaxation properties… Expand

Relaxation of zonal flows in stellarators: influence of the magnetic configuration
The importance of zonal flows (ZFs) in the self regulation of turbulent transport is widely accepted nowadays. Although the ZF evolution is a nonlinear problem [1], involving the nonlinear drive andExpand
