The formation of star clusters is a complex process that involves gas dynamics, gravity, stellar evolution, and feedback across various scales. To accurately model this process, the galactic environment and individual stars within the cluster must be considered. We introduce Ekster, a code that combines the SPH code Phantom, the high-performance N-body code PeTar, the SeBa stellar evolution code, and galactic environment models using AMUSE. It also includes feedback mechanisms, such as stellar winds and supernovae, which play a crucial role in shaping the cluster and its environment. Ekster enables the simulation of star cluster formation, approximating initial components as sub-clusters. Our poster presents the Ekster method and simulation results using either a pre-calculated spiral galaxy model or observations of the Orion Nebula as initial conditions, along with ongoing improvements.
