Macro fan modeling considering cross wind effect
 

Hello fluent users!

I would like to see the effect of cross wind at the fan inlet on the static pressure and fan outlet air velocity.
The problem is the macro fan model in fluent uses a correlation with static pressure and inlet velocity but in this case, the fan inlet velocity is affected by the cross wind and it makes impossible predict the fan inlet velocity.
Due to the computing load of a full 3d fan model, I would like to keep a macro fan model.
Is there any good way to do this simulation?

Many thanks in advance for you!
