In this study, we utilize the SMASH transport model to explore the generation of global angular momentum in heavy-ion collisions. Our results corroborate previous models, highlighting a pronounced peak in angular momentum transfer during mid-central collisions at b = 4 - 6 fm across √SNN = 2:41 - 200 GeV. Additionally, we thoroughly investigate the impact of system size and centrality on angular momentum. Intriguingly, we observe a distinct trend towards higher relative angular momentum transfer in smaller systems and more central collisions. To address local angular momentum conservation intricacies, we propose tailored setups for varying energy regimes, relying on the test particle method and Fermi motion treatment.
