Dense stellar systems are the formation sites of stellar binaries and triples, which can eventually evolve to become gravitational wave (GW) sources. Modelling this process is crucial for uncovering formation channels and estimating detection rates of gravtational wave events from stellar mass objects. Simulating dense stellar systems is challenging due to the multi-physics aspect of the problem. Realistic models should combine gravitational N-body dynamics, Post-Newtonian effects, stellar evolution, rotational spins, tidal dissipation etc. The outcome of such detailed simulations provide not only the astrophysical history of GW sources, but also the initial conditions for fully relativistic simulations of the actual merger. I will present an overview of my research projects in which I gradually increase the complexity of my simulations, ranging from black hole formation, star-gas interactions and dissolution of triple systems.
