description: This study is dedicated to the numerical modeling of dynamic operating regimes of a tokamak using the SOLPS-ITER code. Research into these regimes is essential because, during non-stationary discharges, the plasma configuration undergoes signi-\\ficant changes. In this context, parameters such as temperature and heat fluxes impacting the material surfaces of the vacuum chamber require continuous monitoring throughout the entire discharge period, even if the discharge eventually transitions to a stationary state. This work particularly focuses on analyzing a class of discharges characterized by oscillatory (pulsating) regimes. For such regimes, an accurate dynamic description is the only viable approach. Similar operating regimes of the tokamak have been observed in experimental studies on the ASDEX Upgrade and JET tokamaks. During the modeling of plasma discharge in the ASDEX Upgrade tokamak, oscillations were identified, whose parameters are similar to self-sustaining plasma oscillations previously observed in experimental studies. Further analysis revealed that the SOLPS-ITER code did not adequately account for the dynamics of neutral particles transferred from the EIRENE module to the hydrodynamic component of the package. As part of this study, a modification of the numerical scheme in the SOLPS-ITER code was carried out. The application of the updated version of the package enabled the accurate accounting of dynamic processes occurring in the tokamak plasma and successfully modeled the dynamic operating regime mentioned earlier.
