What's the best way to model supply and extract?

[mechengineer]

Hi there,
I am doing an internal CFD analysis for an office space with Mech Ventilation and I was wondering what's the best way to import supply and extract fans? Is it better if I draw them or import as a component? if the latter applies, what should be the type of the component?

Thanks

using a prototype system allows you to auto-size the network and minimizes the risk of human error with controllers and profiles. But that is about it, you can go either way for setting up your HVAC.

Supply and extract fans cannot be imported directly. You can import boundary conditions (temperature, gains and any macroFlo openings). You can then note the air flow rates from the HVAC results and apply them as a suitable supply and extract boundary conditions in the model at suitable locations.
