Climatic data

Apostolos

Hello to everybody. As I said to my previus message I am new in cfd programms and I haven't yet buy one. So I trying through you to get some real answers (and I really appreciate your time and your effort), cause FLUENT and CFX, try to indicate me that the software of their company is the best solution for me.

I am studying buildings with double skin facades and is important to me to have as inputs for my simulations the climatic data of building's region. This means that I need to have as inputs solar radiation, ambient temperature, humitidy, wind loads to describe the external conditions.

Can FLUENT read climatic data or I have to make my own subroutines with UDF. And if so, really,how easy is to use UDF?
