Add a Cross Wind to a Wind Tunnel
 
Good Morning FOAMers,

I've got a pretty reasonable wind tunnel model running under the Spalart-Allmaras turbulence model and BuoyantBoussinesqSimpleFoam, but now I'd like to add a cross breeze to the tunnel without changing the geometry: imagine a vehicle moving at, say, 10 m/s, in a perpendicular cross wind of 2 m/s.

All of my attempts at setting the appropriate boundary conditions have failed, so I was wondering if anyone out there had input on this.

Cheers,
~Ed
