This paper presents a methodology for synthesizing populations of cataclysmic variables (CVs) using the MESA stellar evolution code. We construct a grid of binary systems with varying initial white dwarf progenitor masses, companion star masses, and orbital periods, and evolve these systems through pre- and post-common envelope phases. Preliminary results reveal diverse evolutionary pathways, including standard CV formation, mergers, double white dwarf formation, and systems that bypass Roche lobe overflow. These outcomes underscore the complexity of binary evolution and the need for refined models, particularly for common envelope ejection. We discuss the implications of our findings and outline future work incorporating statistical distributions for initial binary parameters to generate synthetic CV populations that can be compared with observational data, thus aiming to improve our understanding of CV formation and evolution.
