The High Field Density Region (HFSFD) has been experimentally observed in both divertor and limiter tokamak devices. In order to numerically reproduced the HFSHD region device J-TEXT, we first performed SOLPS-ITER simulations on J-TEXT with activation of drifts, which is associated region. validated physical models, from ASDEX Upgrade (AUG) modelling including full drifts currents, were applied. Through a gas puffing rate scan, attached detached regimes obtained AUG limiter. key plasma parameters are evaluated without that have qualitative performance like except roll-overment total ion flux at targets. drift effects target profiles investigated maximum electron temperature outer targets 15eV 5eV respectively. When divertor, result partial detachment inner regimes, decrease However, for limiter, only decreases far SOL effect neutral density also presented.
