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