Orbital Stack uses a credit system to manage usage. There are two types of credits:

AI Credits: Used for AI simulations, with one AI-Credit required per wind direction (e.g., 8 credits for a typical 8-wind direction simulation).

CFD Credits: Used for CFD simulations, with 7 CFD-Credits needed for a Wind Only Analysis and 10-14 CFD-Credits for a full analysis, which includes wind, solar, and thermal comfort (2-4 Seasons).
