I have to use Ansys to find out the relationship and interaction of building and wind. With this, I need to produce two models with same height and different shape(eg, square and circle), but i am facing some difficulties to create the domain and model as I am totally new in Ansys. I am confused with air domain and fluid domain, which domain should I go for and the way or creating them are the same?

Anyone mind to share with me some link or video which could help me to have a good start in this field please? I really needs help and is kind of urgent. Thank you so much and much appreciated for that. Thank you!
