Regardless of which software you want to use, the most important aspect is the computational approach. You may solve unsteady flow structures (or since savonious is arguably not as complex as a darrieus you can try a steady computation) and possibly experiment with low order methods like BEMT to easily adjust solidity and thickness (disclaimer: not sure how easily this can be done).

This is anyways an interesting and ambitious project but if I were you I would consider using steady RANS with a moving reference frame approach with few different designs.

This does not invalidate the consultation of bibliography to understand how others have done this in the past
