Autodesk Revit to Autodesk Flow Design for Air Flow and Natural Ventilation Analysis 

Unfortunately Autodesk stopped this software last year. We are waiting for an alternative to be announced soon hopefully.

The velocity can be changed from the wind tunnel settings. And the orientation of the air flow itself cannot be changed but you can change the building's orientation so it is the same thing but different method.

Unfortunately autodesk flow design has been discontinued ... autodesk does not have a replacement yet

@@IslamMashaly Thx. Do you still use Flow Design for simulation?

Yes I do because the account is still working but I am looking for other alternatives at the moment but nothing as simple straightforward and with an integrated workflow as flow design

Islam Mashaly thx! I am using CFD for simulating the airflow. But it takes lots of time to setup the boundary condition to get a precise result.😂

You can download it from Autodesk website if you have an educational account. Just search for Autodesk flow free download in google. It should be the first link. However keep in mind that they will discontinue providing the software in 2020 for upgrade reasons i guess.

@@IslamMashaly if that will be discontinue soon, have you known an alternative application that can makes wind simulation like that ?

@@danyazka CFD can do that, but my computer can not open CFD
