How to model internal forced air in a closed box?

Hi there,

Basically I have a display module inside of a box. I want to put forced air inside it going at 2m/s.

I know that FloEFD has fans to deal with this, however I cannot seem to understand how to specify the air it pulls in to go at 2m/s.

If there is an easier way to do this, please advise.

Thanks in advance.
