I am using fluent to model low Reynolds number flow over a wing the BCs are:

velocity inlet: for inlet face

back pressure: for outlet face

symmetry: wing root side face

and the other three faces (upper lower and tip_side) are freestream

I could not find free stream case in the BC list.

Any suggestion, please.

Symmetry. Or wall but set the shear as zero.
