Urgent Butterfly step by step tutorials

Hallo.I am pretty new in Grasshoper and Butterfly.I have a main project that is mainly about butterfly. Unfortunately the videos I met online from Mostapha Sadeghipour Roudsari are already deeply(like for experts)
My project details are: I have a swimming pool in a room with different air conditions( in 2 of them air enters the swimming pool hall and the other 2 let air go outside) so I need to evaluate the indoor airflow taking into consideration the temperature of the pool.Please any help with some tutorials examples on how to proceed?
